Looser neutral PID

• Loosen all IS_NOT_H selections to 0.2 https://indico.cern.ch/event/1495991/#preview:5316296
• Remove all IS_PHOTON selections except in make_rad_photons (this variable is only appropriate for high-ET photons)
• Remove all CALO_NEUTRAL_1TO9_ENERGY_RATIO selections which are very correlated with other PID and make calibration more complicated
• make_rd_detached_etaprime:
  • Correctly implement p(pi)>1GeV and DOCACHI2<10 cuts
  • Remove E(gamma)>100MeV cut
• make_rd_resolved_pi0s:
  • Tighten pT cut 250MeV->1GeV in line with standard Run2 selections
• Remove make_rd_merged_pi0s that is not being used anywhere
• BToLLGamma
  • Tighten cuts to L_MINIPCHI2>12, LL_VCHI2<9, B_IPCHI2<12
  • Refactor code

This is not only impacting radiative modules but since there is an interplay with existing changes to radiative modules I think it's best to include it all together.

The tighter kinematic and DOCA cuts are able to offset the looser PID. Rate -52Hz, bandwidth -1.9MB/s (below only lines with non-zero rate change)
