AthenaServices: Update the AuxSelection/Veto logic in AthenaOutputStream
@goetz reported that when producing multiple streams in standard reconstruction, e.g.
DAOD_IDTIDE, those dynamic variables that should only appear in one (
DAOD_IDTIDE), such as
IDTIDE1_biased_PVd0Sigma, appeared in the other stream as well (
While investigating, I noticed that when the user provides an exclusion list for a given stream via the syntax
Container.-A.-B all works fine but when we have an inclusion list via the syntax
Container.A.B we were ending up w/ unselected dynamic variables. As far as I can see, the veto list that we obtain by
flipping the selection list doesn't contain items that should be excluded. In order to work around this, we now build the veto list explicitly by looping over all dynamic variables and inserting those that are not selected into it.
