  Hi @oboenteg @sbelin, here is a Draft version of the PbPb bandwidth test. The plots-per-page are temporarily disabled (needs some refactoring from the BW side of things), but the rest should be functional. We will do a BW-side review in parallel to help speed this up.

  Can you have a look through and let me know if you see any glaring errors? Can you also check the option files I have made in the corresponding Moore MR. These are currently set up for the 2024 configuration, and should be easy to update. In particular, there is now Hlt/Hlt2Conf/tests/options/bandwidth/hlt2_bandwidth_input_PbPb.yaml which will need things like input rate adjusting.
