Add bids-validator "extractor"

[yarikoptic]

After we add fuse support for extracting per file metadata.

Where can we find this extractor?

[yarikoptic]

there is none yet. There is https://github.com/bids-standard/bids-validator . I think it can (or can be made to) produce JSON output and may be even with some well defined (in jsonschema or linkml) schema. Then we could just do minimal wrapping as "datalad-metalad extractor".

[yarikoptic]

note: this is nothing to immediately do - just an idea we ran by at breakfast with @ericearl since they also do that already, and I thought that datalad-registry would be great platform to formalize/automate it longer term.

New deno validator has --json option:

❯ ./bids-validator-deno 2>&1 | grep json
  --json                        - Output machine readable JSON

@yarikoptic The old ("legacy") validator has the --json option as well. I will try to push a release of the stuff we talked about before to GitHub in the next two weeks. Adding it to my to-dos now.
