Track provenance of derived files

[tsalo]

Summary

BIDS Derivatives includes fields to link derived files to earlier ones (e.g., the preprocessed fMRIPrep file) and the originals in the raw dataset. We should attempt to track this information and include it in xcp_d's sidecar files.

I think the best way to handle it is this:

1. Set the BIDSVersion in dataset_description.json to 1.8.0 (first release after addition of BIDS URIs).
2. Add DatasetLinks field to dataset_description.json pointing to preprocessed derivatives (e.g., "fmriprep": "relative/path/"). I think we'll need some fancy logic to determine the relative path though...
   • Actually, I think we can just use the relative path from the xcpd_dir.
3. Use BIDS URIs for Sources field in sidecar files. E.g., bids:fmriprep:sub-01/ses-01/func/sub-01_ses-01_task-rest_desc-preproc_bold.nii.gz.
4. Retain metadata from source files, when available.

I probably should have closed this with #966.
