ALS Laser End Y

Similar to what was done in alog 40394, we needed to shift the ALS laser in the Y end stations by ~16.2GHz (-5.39V on the crystal temperature control voltage) to bring it close to the PSL. This offset was then relieved using the front panel potentiometer. The crystal temperature now reads 29.4°C.

The ALS autolocker is working again.
