CepGen generator interface

[forthommel]

PR description:

This PR introduces an interface to the CepGen central exclusive processes event generator described in Comput. Phys. Commun. 271 (2022), and introduced at a CMS-PH generator meeting last October.

It is shipped with generator fragments for a LPAIR and a PPtoFF single-dissociative generation. The earlier also demonstrates the interfacing of Pythia 6 for the fragmentation of dissociative beam remnants into a hadronic shower.

Requires CepGen v1.2.0, added to cmsdist in cms-sw/cmsdist#9030.

PR validation:

Shipped in generator fragments seem to be producing something consistent :-)
