GN3 in PHYS

Adds a series of GN3 models to be dumped in DAOD_PHYS:

• Adds 4 new taggers:

  • GN3V00 - utilises only jet and track inputs (same as GN2v01)
  • GN3PflowV00 - jets, tracks, and neutrals particle flows
  • GN3MuonsV00 - jets, tracks, and muons
  • GN3PflowMuonsV00 - all of the above

• Dumps all variables for all 4 taggers above, as well as flipped versions, in FTAG1.

• In PHYS, only dump the 4 variables pb, pc, pu, ptau for the first 3 taggers + flipped versions, but dump all variables (pud, ps, pg, pquark) for GN3PflowMuonsV00

  • These variables are only stored in the jet container, not the BTagging container

• Fixed bug where only the first tagger for a given jet collection was read when running on the jet (not BTagging) collection

• Once validated, move models from dev path to main path and modify code accordingly

• Freeze the GN3 scores
