Updates to xAH for Trigger-Level Analyses from GitLab-hosted fork

[mamerl]

Changes include:

• Modifications to JetCalibrator to allow HLT jets to be re-calibrated with custom changes to JetCalibTools in Athena (Athena changes not yet in main ATLAS repo, but upstreaming changes is planned)
• Modifications to helper functions & classes to allow booking different variations of histograms, etc.
• Changes to BasicEventSelection to handle differences in trigger decision handling between physics_Main and physics_TLA data
• Various other updates, includes some changes already in UCATLAS due to merging UCATLAS main with downstream TLA xAH fork (maybe these need to be removed from the request somehow to prevent changes to all files?)

Hi @mamerl ,

It looks like this is starting from an old version of xAH- there are a lot of changes listed, and some of them (such as removing AF3 support) seem to be undoing updates that have been made in the meantime. Would it be possible to rebase this onto a more current version of xAH?

Best, Michael

Hi @mdhank,

Thanks for pointing that out. I'm in the process of doing a rebase at the moment so will sort that out and mark this PR as a draft until I have done so.

Thanks, Max

Hi @mdhank,

It appears that the rebase didn't work because of some issues with the history for our branch. I'll try to hunt through our commit history and start a new branch from the HEAD of main on my fork of xAODAnaHelpers then will patch the commits for our changes over.

In the meantime, I'll close this PR.

Thanks, Max
