Add APA7 bib style for movies/films

[k127]

So, if example data in Biblatex format would look like this:

@movie{scorsese1976,
  author    = {Scorsese, Martin}, 
  year      = {1976},
  title     = {Taxi Driver},
  publisher = {Columbia Pictures},
}

And was easily converted to CSL-JSON using pandoc,

cat "bib.bibtex" | pandoc -f bibtex -t csljson -o "bib.json"

resulting in:

[{
  "author": [{"family": "Scorsese", "given": "Martin"}],
  "id": "scorsese1976",
  "issued": {"date-parts": [[1976]]},
  "publisher": "Columbia Pictures",
  "title": "Taxi Driver",
  "type": "motion_picture"
}]

In the reference list, that entity type (motion_picture), according to the APA Publication Manual, sec. 10.12, 7th edition,¹ should appear like this:

Scorsese, M. (Director). (1976). Taxi Driver [Film]. Columbia Pictures.
