Adds 2 new methods to convert between screen pixels and geographic coordinates.
As noted in the docs, the toScreenLocation() method rounds on web (AFAIK there will only ever be full pixels on web) but not on iOS and Android, as at least on iOS mapbox_gl also uses half pixels.

I also deleted the bitmap.dart file which was an artifact from the very early days of the plugin but wasn't used anywhere.

Closes #361

BTW, there is some latency issue with those projection methods, not that because of the wrong implementation on the flutter side, but on the mapbox itself, trying to implement real-time map following flutter widget markers. cannot get the realtime purformance.

* Listen to OnUserLocationUpdated to provide user location to app (flutter-mapbox-gl#237)

* Listen to OnUserLocationUpdated to provide user location to app

While the `myLocationEnabled` property is set to `true`, this method is
called whenever a new location update is received by the map view.

iOS only, needs Android. I did check that the location properties
carried here are also provided in Android's [Location][1] object.
