Include Dijets in categorisation script (w/ overlap removal)
We should include the possibility of also using dijet as another source of background for the optimisation of categories. Entry point: https://gitlab.cern.ch/HiggsDNA-project/HiggsDNA/-/blob/master/scripts/categorisation.py?ref_type=heads#L151-153
We also need to include overlap removal. The recipe is given in Hgg_News_20112023
If gamma+jet Pythia (norm):
- Dipho Sherpa: keep everything
- γ-jet Pythia: remove p-p, Keep the rest and classify p-f and f-f
- QCD Pythia: remove p-p, Keep the rest and classify as p-f and f-f
If gamma+jet Madgraph (exception):
- Dipho Sherpa: keep everything
- γ-jet Madgraph: remove p-p. Keep the rest and classify p-f and f-f
- QCD Pythia: remove p-p and p-f
