SEI BS ST2 isolated by ISC_LOCK guardian
Attached is a comparison of the GS13s with stage 2 isolated (blue) vs damped (red).
We still haven't seen the impact on DARM, but I've added this to the ISC_LOCK guardian similar to the way it is done at LLO. This means I also changed the nominal state for SEI_BS to FULLY_ISOLATED

This makes no apparent difference in the DARM spectrum.
