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.

If `nf_min` was not present, then `nf_max` would be left remaining
because an attempt to nuke `nf_min` raised an exception.
Thanks to codecov.io for making it easy to spot this on the coverage
page.
-add f_min & f_max frequency definition in amplifier json
-improve interpolation algorithm to support length differences between the spectrum information and the amplifier ripple and dgt frequency definition

new code provides default values when attribute is missing in the
eqpt_config.json, which can cause unexpected beahaviour
=> provide a warning message when a missing attribute is set to a
default value.

with this feature, spacing is checked with respect to eqpt library
instead of hard coded values in equipment +
mode selection is based on the minspacing instead of a coef or margin on baudrate value
some sanity check are introduced:
- request spacing must be greater than min spacing
- tsp baudrate must be smaller than min spacing

if mode is not given, the program automatically choses the first mode of the tsp
that has the highest bitrate and baudrate
- propagation for each loop on baudrate, no proppag in the loop on the mode
(same propoagation applies for identical baudrate)
- starts with the highest baudrate
- Make power and nb-channel optional fields
- power uses defaulf power in SI
- nb channel computed based on min max frequency and spacing

new field 'out_voa_auto': true/false in eqpt_config json for elligible
amplifiers
if the field is set to true and the power_mode (in
eqpt_config[Spans]) is also set to true, a VOA value is calculated based
on available gain and power margins (EOL) to maximize amplifier gain and
improve its NF

* toggle true/false in eqpt_config json file to allow the use of a given amplifier type in automatic design: eqpt_config[Edfa][allowed_for_design] : true/false
* automatic design is picking the best amplifier (gain, NF constraints)
among the available ones: if toggle to false, the type is deemed non
available. Only alternative before this feature was to remove the
amplifier from eqpt_config library.
* if set to false, the amplifier type can still be input in the network
topology file: it will be recongized.
