Add a few EPOS4 configurations - #2455
Conversation
EPOS4 physics generation always happens internally in the symmetric nucleon-nucleon CM frame. hepmc_rapcms does not change that internal physics, but it applies a rigid rapidity boost (dy = -hepmc_rapcms, applied in src/KW/out.f → fillhepmc) to every particle written to output, which means re-expressing the same collision in the lab frame. This is here used for pO and should be used for p-Pb as well (the shift there is 0.465, from the same `Δy = 0.5·ln(E_p/E_target-per-nucleon` formula).

@jackal1-66, thank you!!
I left a few suggestions in case you want to consider them
