This is a temporary Gen2-only interface to the photodiode readings from
the SLAC Run3 datasets onwards.
Parameters
----------
dataRef : `lsst.daf.persistence.ButlerDataRef`
dataRef of the of the detector/visit to load the data for.
dataPath : `str`, optional
Path at which to find the corresponding photodiode data files.
logger : `lsst.log.Log`, optional
Logger for logging warnings.
Returns
-------
photodiodeData : `lsst.cp.pipe.photodiode.PhotodiodeData` or `None`
The full time-series of the photodiode readings, with methods to
integrate the photocharge, or None if the expected file isn't found.
