Bullseye sensor

An investigation to why the bullseye sensor wasn't working revealed that the cable was disconnected near the MC2_TRANS whitening chassis. A Y-cable is used to add the bullseye channels to this chassis. There maybe two reasons for this: (1) the bullseye cable coming from the PSL is labeled BSC3-CPS-TIMING (sic!) and (2) the DB9 cable connection was free hanging without locknuts. So, the cable may just have fallen out on its own back on 11/10/18. I reconnected the cable and added the locknuts.

In some placed the channels are named PSL-BES_A in other places it is PSL-DIAG_BULLSEYE. Made them all consistent with the former.

The light is currently not centered on the bullseye and one segment is saturating.

The bullseye sensor is fully functional again thanks to the alignment of Peter & Jason, and a new ASC model by Dave.

The medm screens have been updated. The whitening of the input segments is now working as expected, and a RIN channel was added.
