Design aLOG: SEI aLOG 721

Through various levels of changes depending on the whether it was the BSC-ISI, HAM-ISI, or HEPI main library part (see SEI aLOG 721), there are now the following channels in the commissioning frames stored at 256 [Hz]:
HEPIs:
${IFO}:HPI-${CHAMBER}_SCSUM_${SENSOR}_IN_${DOF}_DQ
with ${SENSOR} = either IPS or STS

BSCs:
${IFO}:ISI-${CHAMBER}_ST1_SCSUM_${SENSOR}_${DOF}_IN_DQ
with ${SENSOR} = either L4C, CPS, or STS

HAMs:
${IFO}:ISI-${CHAMBER}_SCSUM_${SENSOR}_${DOF}_IN_DQ
with ${SENSOR} = either CPS or STS
sadly, I only realize after documenting what I've done that the order of "IN" and "${DOF}" is different for HEPI than it is for the ISIs. At this point it's not worth the IFO down time to make the bug fix. Sorry :-(.

This closes out ECR E1500216 and Integration Issue 1046 for Hanford, so I'll reassign it to Monsieur Pele. For Livingston to receive this upgrade, one must only update the following library parts, recompile, install, restart, and restore: 
${userapps}/release/isi/common/models/isihammaster.mdl
${userapps}/release/isi/common/models/isi2stagemaster.mdl
${userapps}/release/hpi/common/models/hepitemplate.mdl

I attach screen shots of the latest version of the relevant blocks in the library parts that I've modified.

Also a bonus change that had been pending until today when I re-found it: the HAM-ISI models had not had their SENSCOR BLRMS channels removed, which I thought have been done when Arnaud was here, as per ECR E1500245 and Integration Issue 1059, but it turns out he only modified the BSC-ISIs (see LHO aLOG 19187). HEPI models never had this calculation, so no need to change there.

For the record, I made sure 
- all SDF differences were understood and captured on all SEI systems before restarting
- all ISC guardians were in their DOWN state, and the IMC_LOCK guardian was OFFLINE before restarting.
- all chambers were brought to OFFLINE via their chamber GUARDIANs
- all chambers were able to be re-isolated after the restart of their front-end process via there chamber GUARDIANs
- add SDF systems for the new platforms have no channels "NOT FOUND" or "NOT INIT" -- because I removed the BLRMS of the STS channels from the BSCs, they required the re-saving and re-loading the SDF table, i.e. an OVERWRITE of the EPICS DB TO FILE, where the file is the safe.snap.
- The IMC recovered after the restart of the HAM2 and HAM3 chambers
