Code update for Run18 embedding (#481)

Patches needed for Run18 embedding are assembled in this PR. These
patches are:
* RDO map is updated and iTPC RDO is added for sector 20 in Run18.
* TpcRS parameters for the second half of Run18 27 GeV dataset is added.
* Offline cluster finder (RTS and StTpcRTSHitMaker) is updated with the
correct gain interface.
* A newer StTpcRSMaker is included to correct the 1st pad row.
