Fixes to ZdcNtuple for injected pulse, plus minor fixes to ZdcRecConfig.py and monitoring
These changes improve our ability to process the ZDCInjCalib stream
- Added injected pulse magnitude to allow processing ZDCInjCalib data
- Removed message about pulser voltage in monitoring (demoted to DEBUG)
- Consolidated ZdcRecConfig into one file again (removing SetConfigFromFlags.py)
