Support null and * in lists in --bids-filter-file

[tsalo]

What would you like to see added in fMRIPrep?

At the moment, it looks like the --bids-filter-file won't convert null and * to Queries when they're in lists within the JSON.

Do you have any interest in helping implement the feature?

Yes

Additional information / screenshots

For example, the following won't work:

{
    "bold": {
        "task": ["rest"],
        "run": [null, "01", "02"],
    }
}

Good catch - we should expand the custom decoding in

fmriprep/fmriprep/cli/parser.py

Lines 96 to 99 in 7032782

	return {
	k: bids.layout.Query.NONE if v is None else (bids.layout.Query.ANY if v == "*" else v)
	for k, v in dct.items()
	}

to expand lists (probably recursively)

I'm adding the same thing to ASLPrep in PennLINC/aslprep#388, so I'm happy to copy it over to an fMRIPrep PR.
