RICH - SIN model updates.
Updates in RichDet related to SIN model updates (Boole!309 (merged)):
- change access methods to the information on SIN (use ratio instead of probability)
- check if the relevant information exists in the conditions DB.
This MR is needed to run lhcb-conddb/SIMCOND!117 (merged) (also will run with the previous SIMCOND versions, with providing a debug info that the relevant parameter with SIN info does not exist).
