Packages tiles for offline use given a Style JSON
The idea with this was that I could pass any arbitrary Style JSON file and create a ZIP file for a given geometry to be used offline.
I discovered, however, that the Mapbox Offline Packs, the standard way to
download offline map tiles in a Mapbox SDK, supports any Style JSON file, not
just ones with a mapbox:// url.
I suppose that should have been obvious in retrospect, that anywhere a
mapbox:// url is accepted, a third-party Style JSON file will be too, but I
didn't realize it.
Because of that, development on this is paused.
