Workaround to avoid passing large energy heavy ions to Geant4

For upgrade heavy-ion productions we were running into the issue that in some peripheral events we have effectively ion split up to smaller parts which still travel close to the beam energy per nucleon. With large enough A these have the energy of more than 100 TeV and from time to time want to interact in VELO vacuum region. In Geant4 energy limit currently is 100 TeV and thus Gauss fails to simulate such events. As these ions in practice should have negligible interaction probability, for productions where one of the beam particles is different from proton we mark all particles with energy more than 100 TeV as documentation particles and thus not pass them to Geant4.
