Calculate theory prediction in certain genLevel bins
Our calculator in https://gitlab.cern.ch/HiggsDNA-project/HiggsDNA/-/blob/master/scripts/fiducial/fiducial_xsec_calculator.py?ref_type=heads should be extended to calculate the prediction for the fiducial cross section per gen-level bin.
The https://gitlab.cern.ch/HiggsDNA-project/HiggsDNA/-/blob/master/higgs_dna/workflows/particleLevel.py?ref_type=heads processor should potentially also extended with any new particle-level observables as samples used from that processor should be fed to the calculation of the theoretical predictions per gen-level bin.
