Bd2Dhh HLT2 Line Checks
AProd to run on the HLT2 data output from 2022 to check we're getting candidates and important variables are getting correct distributions.
This will check lines of the form of the form Bd2Dhh, D->hh/hhhh/pi0hh/KS0hh where h can be a charged pi/K. D is D0/D0bar or a Dst0/Dst0bar which goes to either pi0/gamma. Pi0s can be merged/resolved and KS0 can be LL/DD.
However KS0 are currently disabled so the corresponding lines will not be checked yet.
