Major upgrade of singularity container to v45 (see https://gitlab.cern.ch/bendavid/cmswmassdocker/-/commits/v45?ref_type=tags)

Some small corresponding technical updates which are needed (migrate python tensorflow lite usage to new litert package)

Also fix a few array out of bounds accesses (off by one errors) which caused problems after the ROOT/cling/etc update (but were already bugs previously in principle)

Note that critically now we are back to a situation again where we cannot/should not import tensorflow before the event loop (but we no longer need to)

I will see if a reasonable solution can be found to this stripping off symbols, but it might also be ok like this. (if it happens by mistake narf will detect it and give a descriptive error rather than failing mysteriously/unpredictably)

(CI will fail until the new container version propagates to cvmfs)
