Changes to processor

[cmantill]

• Add back JES (single)
• Add BDT inference in bbbbSkimmer for signal region, with variations
• Add GenSelection for V+Jets and Diboson (with matching to quarks for V+Jets)
• Fix JMR/JMS scale/smearing; see:

  HH4b/src/HH4b/postprocessing/postprocessing.py

  Line 322 in 91a83cc

  def scale_smear_mass(events_dict: dict[str, pd.DataFrame], year: str, mass_str: str):

  
  and apply to this function:

@cmantill We need to add the current JMR/JMS scale factors to the processor if we want to use these right?

As we discussed offline @cmantill I think the current approach is fine, unless you want to update it with the new numbers from the Loukas method.
