MuonConfig: Add support for running from RDOs

Currently the RDOtoPRD convertors are only scheduled if input is BS. This should fix this (though if I'm honest, I'm not sure if this is the best way to check if the input is an RDO file, so if anyone disagrees with this approach please let me know).

I tested this locally by running on an RDO file, with python -m MuonConfig.MuonSegmentFindingConfig --run

I've not made a new unit test, since this still doesn't work with RDOs because of an unrelated (I believe) issue:

S:0 E:0 VarHandle(StoreGateSvc+EventInfo[45903698])                                                                                     WARNING  StoreGate/src/VarHandleBase.cxx:848 (void*SG::VarHandleBase::typeless_dataPointer_impl(bool)): could not get proxy for key EventInfo
S:0 E:0 RpcRdoToRpcPrepData                                                                                                               FATAL   Standard std::exception is caught 

I think this should be addressed in a different MR (the first thing I want to check is if RpcRdoToRpcPrepData really needs an EventInfo)
