Translator for the UK National Archives case law archive.

Available at https://caselaw.nationalarchives.gov.uk/.

This follows the example of the existing [BAILII](https://www.bailii.org/) translator for formatting UK case law as zotero entries,
and relies on the LegalDocXML representation of each case made available on the national archives site as a canonical source of metadata.

It will import individual judgments, as well as allowing 'multiple' import on search result and collection pages.
