SEI guardian Updated - BSC-ISI GS13 gain ON/OFF (BS only)

SheilaD, JimW, HugoP,

We updated the SEI Guardian on site. The update only impacts the BS chamber. It is a patch that allows switching the GS13s to low analog gain when in ST2 is DAMPED. The GS13 are switched back to high analog gain when ST2 is ROBUST_ISOLATED. This update was applied to prevent the ISI from tripping during 'kicks' of the BS, which are inherent to the commissioning tasks. Update details can be found in SEI aLog #662

JimW's WP can now be closed.
