Component to reproduce the issue you're fixing

Tilesets argument can now be passed into the offline download create pack call like this:

const options = {
  name: packName,
  styleURL: STYLE_URL,
  tilesets: [
    'mapbox://mapbox.mapbox-streets-v8',
    'mapbox://mapbox.mapbox-terrain-dem-v1',
    'mapbox://mapbox.country-boundaries-v1',
  ], // Any tilesets that should be included in the offline download
  bounds: [
    [bounds[0], bounds[1]],
    [bounds[2], bounds[3]],
  ] as [[number, number], [number, number]],
  minZoom: 10,
  maxZoom: 20,
  metadata: {
    whatIsThat: 'foo',
  },
};
offlineManager.createPack(options, (region, status) =>
  console.log('=> progress callback region:', 'status: ', status),
);

@mfazekas the main blocker on this right now is getting v10 vs v11 working correctly. If you have any input on how that works or any input in general on this PR let me know

@kevinmanncito thanks much and sorry for the late answer, do you still have issue with getting both RN11 and 10 working? On which platform? I think it's fine if this is a v11 feature only, if that makes sense.

Yeah I figured out how to handle v10 code vs v11 code on android. The issue I ran into wrapping this up is in v11 you can't do the style download and tilesets download in the same descriptor like you can in v10. Its gonna require a bit of a refactor in how things are setup doing two separate downloads.
