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
-This file can then be used to run a new simulation just like a normal
json input file

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.

input) finds the optimum power difference between spans

* add input attenuator on all fibers in the network with loss < padding
* 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

min fiber length and the target length is set accordingly to this min
