Add support for realistic RICH PMT encoding and decoding

• Adds various utility classes that use the readout mapping conditions added in lhcb-conddb/SIMCOND!115 (merged).
• Updates the RICH decoding algorithm to support the realistic PMT data format.
• Support for the data format used by current MC samples (RichSmartID streaming) is retained of course, and processing existing MC samples does not require the above DB update. That update is only required to when encoding or decoding the new format.

Requires Moore!586 (merged) and Boole!289 (merged)
