BandQ 2024 EndOfYear resprucing

Several issues to check for BandQ EOY resprucing

1. Whether sideband of basic b-combiners enough for MVA training

2. For b-hadron spectroscopy lines, the hlt2 cut might be tigher than sprucing cut. See https://gitlab.cern.ch/lhcb/Moore/-/blob/2024-patches/Hlt/Hlt2Conf/python/Hlt2Conf/lines/bandq/builders/b_to_jpsiX_lines.py?ref_type=heads#L103 . Probably not an expected feature.
