Lowered SRCL thresh.

I had seen this while sitting with Jim during an initial alignment earlier this week, and Sheila noted that she'd seen it recently too, but we're not getting the LSC POP DC power above the old ON threshold value of 0.4, so SRY never triggers and sends control signal to the SRM, so we keep getting stuck in the Acquire_SRY state of initial alignment.  I have changed the threshold in lscparams for SRXY locking to turn on at 0.3 and off at 0.2 (from the former values of on at 0.4 and off at 0.3).

Sheila notes that we should check (or at least think about) whether this is coming from a drifting of our alignment on the LSC POP diode, and if we need to think about using another diode for SRY or if we need to make sure we're centered on LSC POP.
