SQZ Guardian redudancy removal

M. Todd, C. Compton, S. Dwyer


At almost every state before BEAMDIV_OPEN_FDS, there was a turn_off_sqz() call, which contains some redudancies when jumping to these states.

We removed these calls (except in Down) and added them to the respective checkers for each state. (LOCK_SHG_CHECKER, LOCK_OPO_CHECKER, ETC...).

This should allow the jump between no injected squeezing states without having to call the turn_off_sqz() each time unless something unlocks.

I also added some changes to the blrms in SQZ_MANAGER.py, see alog Zeroing SQZ BLRMS during no squeezing
