Changed the SEI blend switch library | with implications for HLTS estimator models
Original posts: [SEI: 2544] and [LHO: 85857]. 

On [SEI: 2544] I added a new FADER_TO_ZERO part for tests at Stanford. This part smoothly interpolates an input channel to zero. The part lives in userapps/trunk/isi/common/models/blend_switch_library.mdl.
It was committed to the SVN under revision 32734 [on Aug 13th, 2025]. 

Additionally, this change committed an unreported change to the ESTIM_FADER part that changes the naming convention for the switch monitor. The change is mentioned in the last bullet point of [LHO: 85857], but it was accidentally not committed to the userapps svn at that time. The change was:
 
The changes in this library will only affect the SR3/PR3 models and the OSEM-estimator-related medm screens that Brian modified in [LHO: 87331]. No DQ channels are affected, and nothing else is looking at this naming convention.
 
I have already confirmed with Dave Barker so we have the parts are updated next Tuesday [Oct 14th]. For now, the HLTS models, and estimator screens will run with the current version of the blend switch library.
