Calorimeter Calibration

This MR adds the 'CaloRecAlg' algorithm to the reconstruction step which results in the calibrated deposited energy of the calorimeter and preshower channels being accessible via the reco xAOD files. The 'CaloHit' and 'PreshowerHit' branches are added to the reco xAOD which each store the following variables: Edep, raw_Edep, channel, and WavefomLink.

The 'CaloRecTool' is created and used to retrieve the calibration variables that are stored in the following COOL database folders:

• WAVE/Calibration/HV - This is the measured HV values read in from the DCS Oracle database for all digitizer channels. The HV values are only stored when they change by more than 0.1 V. The recording starts from May 1st 2022. (Keyed by time)
• WAVE/Calibration/HV_ref - This is the PMT HV value used when we measured the reference MIP charge. (Keyed by run number)
• WAVE/Calibration/MIP_charge_ref - This is the measured reference MIP charge obtained from doing an analysis each time the calorimeter setup changed (i.e. filter installed). This also changes each time we changed from low to high gain with the filter not installed, that way we can avoid using the HV gain curves when we don't have to. (Keyed by run number)

The 'CaloRecTool' is also used to retrieve the HV gain-curves which are stored in a root file on cvmfs.
