cubicweb-neuroimaging #3670492 get rid of Scan.identifier [open]

The maxsize of 'identifier' is 64.
It's enough to hold the 'SeriesInstanceUID' of a DICOM image. However it certainly cannot hold the relative path of a NIFTI file (which would be the natural idnetifier for such a file).

Two ways to solve this issue:
1. Get rid of Scan.identifier
2. Raise maxsize to 2048 at least.

I'm all for solution 1. I will submit a patch.
