Merged requested to merge dguest/athena:save-all-hits into 23.0
This adds a flag,
BTagging.savePixelHits which saves the full pixel hit collection to the AOD. It complements the existing "trackless" b-tagging flags. It is a more aggressive option intended for lower pt b-tagging studies, especially in the trigger. Might be of interest to @sargyrop, @tmadula, @cpollard, @lbeemste.
I also cleaned up some terrible looking lambda functions in the btagging flags, I couldn't stand looking at them any longer.
