this MR adds a
CscRawDataCnv_p4 converter since we moved from using CSC identifier hashes which reflect the geometrical position of the CSCs to the actual index of the identifier in the vector of identifiers (positional hash) in !26610 (merged).
The content of the
CscRawData still stays as in version
p3, just the meaning of
m_hashId changes from geometrical to positional hash.
