I was just looking at the draw.io packaging in Nixpkgs, and I discovered
that there's already code in there for running headless draw.io! [1]
But it's not exposed outside of this pandoc filter package.  I'm going
to see if it works, and if it does I'll see if we can pull it out to the
top level, as a drawio-headless package or something.
