Description

The function is deleting both asl.nii and asl.nii.gz, when we want to save the corrected asl.nii after xASL_bids_BIDSifyASLNII

Requirements

1. Correctly manage zipping
2. Correctly manage unzipping
3. Don't overwrite or delete when moving to the same file 👍
4. Fix the header to reflect the zipping (we previously claimed that zipping is not handled, but it is) 👍

Release notes

Correctly manage zipping when moving identical files.
