Add Functional GroundOverlayF component

[lkuich]

Please provide an explanation of the issue

Currently there isn't a functional version of GroundOverlay. I've made something small for the interm for my needs, but having a fully featured component would be awesome!

function GroundOverlayFunctional({ url, bounds, options, visible }: GroundOverlayProps) {
  const map = useContext<google.maps.Map | null>(MapContext)

  const imageBounds = new google.maps.LatLngBounds(
    new google.maps.LatLng(bounds.south, bounds.west),
    new google.maps.LatLng(bounds.north, bounds.east)
  );

  const groundOverlay = useMemo(() => {
    return new google.maps.GroundOverlay(url, imageBounds, options);
  }, []);

  useEffect(() => {
    if (groundOverlay !== null) {
      groundOverlay.setMap(map);
    }
  }, [map])

  useEffect(() => {
    if (typeof url !== 'undefined' && groundOverlay !== null) {
      groundOverlay.set("url", url);
      groundOverlay.setMap(map);
    }
  }, [groundOverlay, url]);

  useEffect(() => {
    if (typeof visible !== 'undefined' && groundOverlay !== null) {
      groundOverlay.setOpacity(visible ? 1 : 0);
    }
  }, [groundOverlay, visible]);

  useEffect(() => {
    const newBounds = new google.maps.LatLngBounds(
      new google.maps.LatLng(bounds.south, bounds.west),
      new google.maps.LatLng(bounds.north, bounds.east)
    );

    if (typeof bounds !== 'undefined' && groundOverlay !== null) {
      groundOverlay.set("bounds", newBounds);
      groundOverlay.setMap(map);
    }
  }, [groundOverlay, bounds])

  return null;
}

export const GroundOverlayF = memo(GroundOverlayFunctional);

How does it behave?

No component exists.

How should it behave correctly?

A functional component for modern React should exist.
