FreqArray-Mon is updated much more than the acquisition rate #1

Problem: This PV is update in a much faster rate than the spectrogram acquisition. Probably because of a wrong chain of records being processed.

This has to do with the fact that we were using the Trace-Mon waveform (that is updated as fast as possible depending on the TuneProc IOC parameters) for upating the NELM field of subArray records. This was done as EPICS base was not sending monitors for NORD fields in EPICS < 3.15. This has been fixed according to the RELEASE NOTES (https://epics.anl.gov/base/R3-15/6-docs/RELEASE_NOTES.html). So, we can trivially fix the issue, by just using the NORD field to update the NELM fields in the subArray records
