Follow !3472 (merged).
A Rich Counter is defined as follows:
R --> rich detector
S --> side (defines the plane, up-down for RICH1 and left-right for RICH2)
C --> column (each side is made up of horizontal (vertical) columns for RICH1(2))
M --> module
This merge request addresses a bug. The number of hits in the modules of side 2 was consistently reported as 0 for both RICH1 and RICH2. This number was added to the number of hits in the same module on side 1 instead, resulting in an incorrect hits count on both sides.
Hits are now managed using a map that includes the counter name and the corresponding number of hits.
