PanTau: fix irregular tau decoration
Hello,
This MR addresses the problem reported by @jcatmore in ATLASRECTS-6460: a decoration is added onto some taus but not all. When calling this earlier,
tauJet->setPanTauDetail(xAOD::TauJetParameters::PanTauDetails::PanTau_DecayModeExtended, decayMode_PanTauExtended);
xAODCheckerSummary.py no longer complains.
The rest is just minor opportunistic cleanup that does not affect the output.
Although this MR changes the tau reconstruction output (TauJetsAuxDyn.PanTau_DecayModeExtended), I'm not adding the corresponding label because it's a variable that is used nowhere, neither in the reconstruction nor in analysis. But I do add the bugfix label :-)
Cheers, Bertrand
