React.js Google Maps API integration

# Requires React 16.8+

React hook based on new official way to load googlemaps script.

It's the alternative variant of LoadScript and useLoadScript hook that tries to solve the problem of "google is not defined" error by removing the cleanup routines ([read more](https://github.com/JustFly1984/react-google-maps-api/pull/143)).

```js static
import { useCallback } from 'react'
import { GoogleMap, useJsApiLoader } from '@react-google-maps/api'

const options = {
  zoomControlOptions: {
    position: google.maps.ControlPosition.RIGHT_CENTER // 'right-center' ,
    // ...otherOptions
  }
}

function MyComponent() {
  const { isLoaded, loadError } = useJsApiLoader({
    googleMapsApiKey: "YOUR_API_KEY" // ,
    // ...otherOptions
  })

  const renderMap = () => {
    // wrapping to a function is useful in case you want to access `window.google`
    // to eg. setup options or create latLng object, it won't be available otherwise
    // feel free to render directly if you don't need that
    const onLoad = useCallback(
      function onLoad (mapInstance) {
        // do something with map Instance
      }
    )
    return <GoogleMap
      options={options}
      onLoad={onLoad}
    >
      {
        // ...Your map components
      }
    </GoogleMap>
  }

  if (loadError) {
    return <div>Map cannot be loaded right now, sorry.</div>
  }

  return isLoaded ? renderMap() : <Spinner />
}
```
