Reverting some Cal SDFs, accepting a violin

I've reverted EX cal line amplitudes, as RyanS and Ibrahim have done several times over the last few days. Calibrators, please have a look and change guardian to set these to the values you want.

I've also accepted FM4 of ITMY Mode 9 being off, since that's what guardian seems to have done.  Rahul, please have a look.

I will un-monitor IY mode 9 from the SDF since we don't use this filter bank.

Ah! Right! Forgot that NOMINAL_LOW_NOISE has these gains hard-coded in place such that when we return from NLN_CAL_MEAS they get turned back on. And even worse, this is hidden in lines 261 thru 263 of the ISC_GEN_STATES.py code that the ISC_LOCK.py guardian calls around its line 244. Here's the changed code in ISC_GEN_STATES.py:
259            #make sure cal lines are on
260            for g in ['CLK','SIN','COS']:
261                ezca['SUS-ETMX_L3_CAL_LINE_%sGAIN'%(g)] = 0.3
262                ezca['SUS-ETMX_L2_CAL_LINE_%sGAIN'%(g)] = 50
263                ezca['SUS-ETMX_L1_CAL_LINE_%sGAIN'%(g)] = 35

(lines 262 and 263 had been set to the former PUM and UIM gains of L2 = 35 and L1 = 20, respectively.)

The fixed ISC_LOCK guardian has been reloaded as of 2023-05-15 16:55:18 UTC.
