FeatureRequest: Consumption based current sensor calibration

[TempleClause]

Basically put this formula inside the configurator:
new_scale = old_scale x (OSD_mAh_consumed / mAh_charged)

Is there already something planned like this? Otherwise I might go ahead and write that code.

Something like this? #1439

Similar yes, but instead of putting in the actual current values you would put in the mAh consumed according to the OSD and the mAh you actually put back in the pack.

I guess it could be done in the same window.
