Laser Trips
Please when the laser trips, disable the locking for the PMC, FSS, and ISS. It doesn't make
much sense to keep ramping the NPRO PZT when there's no chance of any of the cavities acquiring lock.

I added a few lines to the LASER_PWR Guardian so that when this node goes to FAULT from a lack of light, then it will turn OFF the autolockers for the FSS, PMC, ISS in that order.
It would be best to write a guardian to do this if it is necessary. There are not always people here when the laser trips.
