Notes on SQZ channels - to incorporate into channel lists

Many thanks to Vicky Xu for these notes on the most DetChar relevant SQZ channels. I've done my best to clean up the info into a formatted list, but I'm really just relaying her knowledge here.

This is not yet a MR, in part because I'm not sure that we settled on a format for per-channel comments (see also my comment here), and in part some additional work is needed to fill in fields and compare with other SQZ lists.

# Channels for monitoring ADF line
; like a squeezer calibration line, sometimes it sweeps
H1:SQZ-RLF_INTEGRATION_ADFEN ; ADF line on/off switch
H1:SQZ-ADF_VCXO_FREQ_SET ; ADF frequency control
H1:SQZ-ADF_VCXO_CONTROLS_SETFREQUENCYOFFSET ; ADF frequency control

# Important SQZ channel details

H1:IOP-LSC0_RLF_FREQ_MON ; (don't know if this has DQ) This is a readback of the filter cavity detuning, this == offset+nominal (below) 
H1:IOP-LSC0_RLF_FREQ_OFS ; (don't know if this has DQ) This is the filter cavity detunign offset from "nominal", where nominal = channel below
