-separate edfa and raman_list of acceptable amplifiers to better
customize criteria between edfa and raman amplifiers
for example min gian requirement: no extended min gain range for raman
amplifiers because there is always an edfa solution, which is better for
small gains.

EOL span ageing was added for each connector "to be fused" span
=> now, EOL ageing is only added to the last span of the fused spans

support min gain for raman auto-design:
raman amplification is only considered for a span if its gain > specified
min gain of the raman hybrid in eqpt_config
auto-design was checked succesfully when enabling a mix of 6 possible different
amplifiers: low gain, medium gain, hybrid ramans, high power and high
gain amplifiers. They were picked as expected.

-Promote incremental and iterative network design
-Automatic saving of a "network-name_auto_design.json" file
-Results of the autodesign (additional amplifiers, configuration) are
saved to this ..._auto_design.json file

new field 'out_voa_auto': true/false in eqpt_config json for elligible

if the field is set to true and the power_mode (in

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.

* create new Fiber attribute: att_in, which is a fixed attenuator for
padding purposes
* define "padding" : 0 in eqpt_config will disable the feature
effectively
