What kind of change does this PR introduce? (Bug fix, feature, ...)

Fixed CDB field lookup name (changed from sepd_calib to mip_calib), changed CDB lookups to use encoded keys instead of channel number, moved cdbttree lookup to InitRun(), and added bad/uncalibrated channel handling.

TODOs (if applicable)

Links to other PRs in macros and calibration repositories (if applicable)

Have you tested these changes against run2auau? Please update your calibration file to use the same structure as previous runs, there is really no need to change things now. Setting a channel to zero artificially based on your fit/calibration factors is dangerous. I would recommend dividing by the average MPV, then use m_TowerInfoContainer_calib->get_tower_at_channel(ch)->set_isNoCalib(true); or other status setters to mark that channel.

Whatever is implemented it has to work across our runs, we don't want separate schemes for run2auau and run3auau.

This PR would break the existing Run2 production and after inserting a reformatted calibration which is compatible with the existing code this PR is not needed anymore

These changes were intended to be a short-term fix only to be used for run3 AuAu calibrations. See PR #3828
