EstherLerouzic 56e615c713 Feat: Use a reference channel per OMS instead of total power for design

Correctly uses the oms band and spacing for computing the nb of channel
and total power for design per band.
In order to keep the SI values as reference, introduce a new parameter
in SI to indicate wether to use this feature or not.

If "use_si_channel_count_for_design": true, then the f_min, f_max and spacing
from SI are used for all OMSes
else, the f_min, f_max, spacing defined per OMS (design_bands) is used.

This impacts tests where the artificial C-band boudaries were hardcoded, and
it also has an impact on performances when SI's defined nb of channels is larger
than the one defined per OMS. In this case the design was considering a larger
total power than the one finally propagated which resulted in reduced performance.
This feature now corrects this case (if "use_si_channel_count_for_design": false
which is the default setting). Overall autodesign are thus improved.
