hed-validator v3.15.0

This version introduces a revamped interface for BIDS dataset validation. The recommended method of validating BIDS data is now as follows:

1. Construct a BidsJsonFile object for dataset_description.json.
2. Construct a Schemas object with buildBidsSchema().
3. For each file to be validated, construct a BidsSidecar or BidsTsvFile (as appropriate) and call its validate() method.

Version 8.3.0 of the HED standard schema is now bundled with this validator.
