Recognise G4 simulated samples better in PRW Autoconfig
Changes explicit list of SimulationFlavour values to pattern-match for "FullG4". Otherwise the autoconfiguration tried to set up AF2 PRW files due to my file's value being "FullG4MT_QS". This should be more future proof, although I could also see an argument for matching some fast-sim tags instead.
