auto design were changed long ago and these functions did not
apply the changes. Besides there was a confusion between request_element
class where loose is a string, and PathRequest from topology.requests
where loose_list is a list of strings.
This patch corrects the naming and also the tests,
because it used the wrong class to gererate xls services

- read per degre roadm-path impairment from roadm sheet
add additional optional columns: type_variety and 'from degrees'
and 'from degree to degree impairment id'
'from degrees' can contain a list of degrees separated with ' | ', then the
'from degree to degree impairment id' must contain a list of ids of the same
length.
Impairment ids are expected to be in the ROADM equipment spec and
from degree must be the previous node (no verification of user input).

Compute the tilts only if raman-flag in sim_params is turned on.
Use actual input power in fiber (according to expected propagation
during design).
Creates a function that computes the expected tilt after propagation
in a span, and returns the normalized power difference at the center
frequency of each band, and the tilt experenced between lower and
upper frequency in each band.
Include the expected tilt when computing target gains of amplifiers.
Current function requires that the bands remain in the same order.
(ordering is ensured when creating the objects).

To ensure that the multiband amplifier meets the required gain and
power targets for each band, this commit introduces a preselection
process for the amplifiers type variety. The preselection ensures
that only compatible amplifiers are considered, avoiding that
an amplifier is selected for one band that is not part of the same
multiband amplifier type variety of the amplifier selected for the
other band(s).

Target setting computation is done going through each element of the OMS
and computing resulting delta power after each amplifier element. In order
to account for different delta power per band (multi band autodesign), the
computation must be made per band. The previous introduction of a standard
name for bands ("CBAND", "LBAND") ensures a stable key to index these
delta power computation.

Introduce a design_band parameter in ROADM and Transceiver.
- if nothing is defined, use SI band(s)
- if design band is defined in ROADM, use this one for all degrees
- if per degree design band is defined, use this one instead
unsupported case: single band OMS with default multiband design band.
Check that these definitions are consistent with actual amplifiers

Introduce a new multi-band element that contains a list of Edfa element:
- reads multiple amps out of the element config.
- deduces frequency band from the amp in the list.
no autodesign yet: multi-band amps must have type_variety.
- checks that type variety of individual EDFAs is consistent with multiband
type variety
- demux and mux spectrum when propagate in multiband
- don't add a preamp or booster if a multiband amp is already defined.
The print of channel number is removed from equipment, since the channel number
may now depend on the path's amplifiers. This changes invocation results layout.

The commit introduces mux/demux functions in amps and ensures that the
propagation is only done on carriers that are in the Amp bandwitdh, ie
with all their spectrum including slot width is in bandwidth.
For consistency, default amp f_min is changed:
Objective is to use amplifiers' band to bound the possible frequencies
to be propagated. Since the current default f_min of Amp in json_io.py is
higher than the SI one, this would result in a different nb of channels
than currently used in tests, and a change in all tests. In order to
avoid this, I preferred to change this value and have consistency
between SI f_min and Amp f_min.
The commits adds a set of functions to make amps band the useable
spectrum on each OMS. Thee OMS generation is changed to use the amp band.
The commit adds filtering functions (demux and mux) to filter out spectrum
which is not in the amplifier band.
Spectrum assignment is also corrected to correctly match the amp bandwidth
constraint with guardband: center frequency index must be within the
usable part of the amp band. This changes a bit the notion of freq_index
and guardband in the functions, but this is transparent to user:
f_min, f_max represent the amp band, while self.freq_index_min/max
represent the center frequency boundary for a reference 50GHz channel.

redesign True means that network is redesigned using each request
as reference channel. When False it means that the design is made
once and successive propagation use the settings computed with this
design.
Default propogation is without redesign, so that path-request-script
must use the ----redesign-per-request option to behave as before this
commit.

This commit introduces the 'type_variety' attribute for ROADM elements,
allowing the use of different types of ROADM specifications instead of
being limited to the default one.
If no type variety name is provided in the eqpt_config, the 'default'
name is used for backward compatibility with libraries. Additionally,
if no type variety is defined in the ROADM element in the topology,
the default one is used for backward compatibility with topologies.
The 'type_variety' attribute is included in the 'to_json' and
'display' methods for ROADM elements.

The parameter was introduced in commit 9736f7c032
but the export to_json was not added.
In the next commits, it is necessary to compute Raman gain during the design
phase. The sim-params used for this computation are updated during the
design phase for speed reasons. To ensure the proper restoration of user
settings for propagation, the export must include all parameters. Therefore,
this commit adds 'computed_number_of_channels' to the JSON export. This allows
for the accurate recording of all user settings locally and enables their
restoration.

while tilt target is still defined vs wavelength (common usage).

- Replaced multiple calls to the span_loss function
with recording the span loss result in the fiber elements,
reducing computation time.
- Updated Raman gain estimation based on design target powers to ensure
accurate Edfa gain calculation or gain reduction during design.
- display the computed and design Raman gain in RamanFiber string output
- do not add padding on Raman fibers
- Added to_json function to preserve user input SimParams values,
which were previously overwritten by initializing SimParams
with fake values during design.
Next step is to allow users to balance computation time and
target accuracy of the design by inputing their own SimParams
and ref channels design values.
