CV output calibration

[tehn]

in the case of CV channels not matching it'd be helpful to have a command that stores a calibration value to flash (and is automatically used in future bootups)

ie CV.CAL 1 100 which has the effect of an additional offset.

+1 - might be a separate feature but I’m also experiencing scaling issues (differing ‘bad’ offsets for a single output depending upon what the output voltage is)

+1 via support

Here is an incomplete implementation of the calibration op strategy proposed here; I got stuck on deciding exactly where the calibration data should be stored.
