hello muon experts,

i file this bug report to document the missing overlap removal for the muon variables in the tag file, if the bug report is filed in the wrong area please consider moving it.

the problem that we want to fix pretty urgently for the tag reprocessing in release 16 is to only store each unique muon once in the tag file, so some overlap removal between the staco and the muid family needs to be made (the 4-vec is anyways so similar that it really doesn't matter which one is chosen). there is some overlap function already implemented, but it is not doing its job:

oliver also mentioned to jamie that he has a piece of code to fix it. it would be great if we can do this really quickly, maybe for the thursday dec 9 tag deadline? thanks!
