Enable dcm2niix's BidsGuess

[Dan Levitas]

dcm2niix version v1.0.20230731 and later will insert the field BidsGuess into the JSON sidecar files (see here). ezBIDS and BidsGuess both do a good job of discerning the datatype and suffix information from data, but I've come across a few datasets where BidsGuess performs better. We should therefore enable this into the ezBIDS Core. ezBIDS will continue performing its entity label mapping, but datatype and suffix identification will be handled by BidsGuess if the uploaded data are DICOMS (or eventually, NIfTI/JSON files converted from dcm2niix version v1.0.20230731 and later).
