Extend comparison tests on main after merging

Currently, on main the Be comparison from the MR pipelines is re-run one-by-one. Can we extend this with e.g. using the longer testvectors as input signals.

Ideas:

• check if different operating points are non-be with the longer testfiles than with the shorter ones (easy first step could be comparing the number only)
  • would require either hacking the pytests or creating a more flexible way of specifying the input files for the modes
• just check for crashes with the longer testfiles
  • basically just runIvasCodec.py
