LArElecCalib correction handling
Two improvements related to the corrrections-handling in the LAr Electronic Calibration chain:
- Better log-messaging by LArCalibPatchingAlg
- LArOFCAlg: Revert input CaliWaveContainer back to its original (uncorrected) state after processing
The latter can be considered a bugfix: Without this change, the output POOL file (and ntuple) contains only the corrected values, the uncorrected ones are lost.
Note for the review shifter: This code does not run in any production (or CI test job), only the LAr calibration procedure.
