Merged requested to merge nwarrack/athena:warrack-master-BSconversion_tgc into master
Decouple the BS conversion from the RDO->PRD decoding for the Muon Spectrometer TGCs by removing the BS convert function and replacing it directly in the trigger algorithms prior to the RDO->PRD decode function.
This work is carried as part of the AthenaMT migration, specifically to allow the BS conversion to be carried out completely separately from the RDO->PRD process. The BS conversion can then be carried out by trigger and offline in the same manner.
The work has been tested by running the unit tests in the MuonConfig and TrigValidation packages as well as running the q221 Reco_tf.py test and comparing the output myAOD.pool.root leaves with acmd.py diff-root
