Extend support for RICH MC cheated reco from XSIM data

Requires LHCb!4255 (merged) Moore!2602 (merged)

• Adds example options to run directly off XSIM files, by-passing Boole step. This is run with

> gaudirun.py /path/to/Rec/Rich/RichFutureRecSys/examples/{RichFuture.py,data/PMTs/MCFormat/MCXSimFiles.py}

• Extensions to monitors / counters specific for 4D reco.
