add onCameraIdle method like google map

[masoudpaidar]

There is onPositionChanged option in flutter_map but it gets called every time the position is changing, which is a lot. As soon as the user touched the screen, the onPositionChanged gets called until the user stops touching the screen,
but there is no option to call a method when camera movement has ended like a onCameraIdle in the google map

In #719 you can listen to events

  StreamSubscription<MapEvent> subscription;

  @override
  void initState() {
    super.initState();
    mapController = MapController();

    subscription = mapController.mapEventStream.listen(onMapEvent);
  }

  void onMapEvent(MapEvent mapEvent) {
    if (mapEvent is MapEventMoveEnd) {
      // do something
    }
  }

  @override
  void dispose() {
    subscription?.cancel();
    super.dispose();
  }

@jiazeh is right.

I'll soon finish that PR (little docs + fix when no event triggered when mapController.fitBounds called), I was a little busy :)
