Event format stream specific content

In the simulation group meeting last week it was highlighted that now that we write stream-specific event format objects we should also only add objects written by that output stream. This tries to accomplish this by using the DataHeader to get the list of keys (branch names) and type names (via class ID).

@berghaus I've been performing the validation of our framework in R22, starting in the nightly this MR is associated with, we see errors in the first event of the event loop like:

VarHandle(StoreGateSvc+PAOD_2LDF[222376821])                WARNING StoreGate/src/VarHandleBase.cxx:848 (void*SG::VarHandleBase::typeless_dataPointer_impl(bool)): could not get proxy for key PAOD_2LDF

Now, I'm not sure if the errors to do with the changes introduced by this MR, but this is the only MR in the list (looking at the titles) which seemed to change something relating to output streams (in our case, "PAOD_2LDF"). Does the error we are seeing make sense or seem related? If so, do you know what we have to change to get things working again?
