contains method for LatLngBounds class

@istarkov what do you think about .contains() method for LatLngBounds(https://github.com/istarkov/google-map-react/blob/master/src/utils/lib_geo/lat_lng_bounds.js) class. Like this: https://developers.google.com/maps/documentation/javascript/reference#LatLngBounds

@istarkov ok, thanks.

i just drop it here 😄 :

   handleMapChange({ center, zoom, bounds, marginBounds }) {
       bounds.sw = { lat: bounds.se.lat, lng: bounds.nw.lng };
       bounds.ne = { lat: bounds.nw.lat, lng: bounds.se.lng };

       const googleLatLngBounds = new google.maps.LatLngBounds(bounds.sw, bounds.ne);

       googleLatLngBounds.contains({ lat: Number, lng: Number }); // boolean
   }
