Updated ParticleID to handle new PDG conventions for reco14-patches.
Update of the ParticleID class to handle the current PDG ID numbering conventions, as well as expand the class to handle BSM physics models that are typically used in Pythia 8. This also mitigates the segfault which was reported in LHCBGAUSS-770 (and which happens also in Brunel).
