When loading the equipment file in json_io.py we should raise an error
if an Edfa type_variety specifies a NF type_def that is not
implemented. This should also allow to remove the assert statement in
the _nf method in the Edfa class.

Currently, the RamanFiber class does not implement its own to_json
method but inherits it from the parent Fiber class. This means that
operational parameters (temperature and raman_pumps) are not included
(and therefore not picked up by the network_to_json method in
json_io.py). So if a user saves the topology, e.g. using the
--save-network option, and later uses that saved topology as input,
the result will be wrong.
This patch includes the operational parameters in to_json.

- add the per degree info using the EXACT next node uid as identifier
of the degree when a node is a roadm
- add the degree identifier on the propagate and on the call functions
- use the per degree target_pch_out_db defined in json entry for the
target power in network build
- verifies existence of the per degree power target in order to support
partial per degree target power definition
- correct test data files for expected auto design results that now
should include the per degree information, even if it is the same
for all degree.
- in order to enable per degree power definition on direction where
booster is not defined, enable the declaration of edfas in json without
specifying type variety

This is effectively a revert of commit 771af49 which added a
commented-out feature for printing out carrier info of the first hop.
On one hand, I'm reluctant to remove this, because apparently this was
not added by an accident, the PR #193 explicitly speaks about a
suggestion from Dave Boertjes for this feature -- and the git history
with merges looks like this one was actually pulled in as a single
commit. On the other hand, it is apparently not used anywhere, and all
of the required information is already available in some other manner --
for example, one can easily follow the path and add these prints to the
propagation, or just walk the path manually.
Digging further, I removed some of similar print() statements in
acafc78, and then restored some commented-out print()s via ec9eb8d (also
see the discussion in #299), which were then removed by Esther in
8107dde. So my TL;DR version is that this is dead code, and that
apparently the *real* use case is having total insight into the spectrum
info along the path (e.g., #246). That should, IMHO, be handled by
proper processing of the resulting data in a nice UI.

That class is an internal implementation detail, so mark it with a
leading underscore as per Python idioms.
Also, tweak the docs so that there's less duplicate information and
more cross-references.

This mainly reverts some auto-fix-ups done in
I2f0fca5aa1314f9bb546a3e6dc712a42580cd562 which do not make that much
sense. By reverting them by hand, it's (hopefully) easy to see what is
just a tool work and what is an opinionated preference.

Currently interpolation of nf_ripple or gain_ripple fails if the length
of the input list is different from the dgt input list since the amplier
frequencies used for interpolation are calculated based on the length of
the dgt input list. There seems to be no good reason for this restriction
so I propose to calculate amplifier frequencies separately for the
different inputs. This also allows to specify a flat ripple with just one
number and a flat dgt with two numbers.

Currently the string representation of some elements in elements.py refer to parameters that are not assigned until the propagate function runs.
Printing an element or trying to access its string representation before propagation therefore raises a TypeError.
This patch should fix the issue.

This might have nothing to do with the ITU frequency grid (it's really
just about a uniform distribution), so let's give it a more readable
name and more readable parameters.
Both of these places referred to "eq. 123 from arXiv:1209.0394", the
only difference (apart from the source of the input parameters, beta2
and asymptotic_length) was calling the two branches "SCI" and "XCI" vs.
"SPM" and "XPM".
In this commit I've only moved the code to a single implementation. The
input data are still being read from the same parameters, of course.
For some reason, the code allowed using "convenience names" for
accessing properties since commit 58ac717f. To me, this looks like an
obvious anti-pattern because accessing a single property via three
different names only makes the code less readable. Let's kill this
"feature".
In case of the `Power` class, the code used "ase" and "nli" on the
majority of places, so let's use these abbreviations instead of their
spelt-out variants.
SpectralInformation was "clean" already, but there were calls to the
`update()` wrapper around the `namedtuple._replace`. Given that there
were no property aliases, it's safe to just call `_replace()` directly.
In case of the `Pref` class, once again always use `p_span0`, `p_spani`
instead of `p0` and `pi` -- it's a trivial change.
Rather than do the None-dance and document the default value within a
docstring, let's use the default value directly. This is safe because
numbers are immutable.
Because default arguments are evaluated *once*, not every time they are
called, a mutable default value is not "reset", and this happens:
>>> from gnpy.core.node import Node
>>> x=Node('123')
>>> y=Node('456')
>>> print(x.metadata)
{'location': Location(latitude=0, longitude=0, city=None, region=None)}
>>> print(y.metadata)
{'location': Location(latitude=0, longitude=0, city=None, region=None)}
>>> y.metadata['foo']=123
>>> print(x.metadata)
{'location': Location(latitude=0, longitude=0, city=None, region=None), 'foo': 123}
This is easily fixable by using an immutable value as a placeholder
here.
This feature is intended to support designs such as OpenROADM where the
line degree integrates a specific preamp/booster pair. In that case, it
does not make sense for our autodesign to "pick an amplifier". The
restrictions can be activated by:
- Listing them in `eqpt_config.json`, so that they are effective for all
ROADM instances.
- On a per-ROADM basis within the Excel sheet or the JSON definitions.
Restrictions apply to an entire ROADM as a whole, not to the individual
degrees.
If a per-degree exception is needed, the amplifier of this degree can be
defined in the equipment sheet or in the network definition.
If no booster amplifier should be placed on a degree, use the `Fused`
node in place of an amplifier.

While the `itufl()` function uses THz by default, its values depend on
the frequency range that is passed via arguments. In this context, the
f_min and f_max come from the default SpectralInformation which is in
Hz.
