Updating CAL-CS LSC (auxiliary DOFs) filters

WP 8302

I wanted to get some calibrated spectra of the MICH/PRCL/SRCL degrees of freedom and noticed that the DRMI FOM - i.e. the plot on nuc 4 was not calibrated correctly. The first thing to fix was the outdated actuator filters in the CAL-CS model (the no longer matched the filters that were engaged for BS/PRM/SRM).

While Jenne and Cheryl were relocking today I switched the filters to what I think they will be (will confirm once we are fully locked again).

This has caused several SDF diffs in CALCS which I have already accepted in the safe snap but will need to be accepted before we go to observe.

Apparently they are not monitored in Observe, because once we got to NLN, there were no SDF diffs.
