Feature request: add a check for saturations in analog boards (CM, IMC)

We have had a series of locklosses due to saturations in the IMC board, which we can easily identify by looking for times when H1:IMC-REFL_SERVO_SPLITMON hits 10 volts, which was happening about 1 or 2 seconds before the lockloss. can we add a check for this into the automatic lockloss checks?

There are a few similar channels, which should not reach 10V while we are locked that would also be worth checking. H1:IMC-REFL_SERVO_FASTMON H1:IMC-REFL_SERVO_SUMMON H1:IMC-REFL_SERVO_SLOWFBMON H1:IMC-REFL_SERVO_SLOWMON

H1:LSC-REFL_SERVO_SUMMON H1:LSC-REFL_SERVO_SPLITMON H1:LSC-REFL_SERVO_FASTMON H1:LSC-REFL_SERVO_SLOWFBMON H1:LSC-REFL_SERVO_SLOWMON

These are the kinds of things which shouldn't have their own plot for every lockloss, because most of the time they probably aren't saturating, but if we could set up a flag or something for the times we do saturate these before the locks.

It would also be interesting to be able to run this for the past locklosses, and identify how often we have been loosing lock from this in the past. (This is just for curiosity for now, but in the future it will be very useful when we identify a new lockloss to be able to look back at a collection of locklosses over the last few months and see how often that type of lockloss is happening).
