• feat(core): render the map as a globe when the style sets "projection": {"type": "globe"} (#4533).
• feat(ios): with rotateEnabled, drags and zooms on the globe turn the bearing with the planet, so the place under the finger stays under it over the poles and nothing spins about them (#4533).
• feat(ios): -[MLNMapView isCoordinateOccluded:] tells whether the globe hides a coordinate, for views placed over the map (#4533).
