Remove use of old RICH framework
Adapts to Rec!818 (merged)
Note this MR just allows Panoramix to build. I have not addressed any runtime options or references to the RICH in the various menus. I will leave that part to others.
Also note I had to pull in the updates in !10 (merged) and !11 (merged). It would be good if in general MRs are not left too long before getting merged.
