Also added a useController hook which exposes the parallaxController using React hooks.

Usage example:

import React, { useLayoutEffect } from 'react';
import { useController } from 'react-scroll-parallax';

const App = () => {
  const { parallaxController } = useController();

  useLayoutEffect(() => {
    const handler = () => parallaxController.update();
    window.addEventListener('load', handler);
    return () => window.removeEventListener('load', handler);
  }, [parallaxController]);

  return (
    <div>
      {'...'}
    </div>
  );
};

@jscottsmith any thoughts on this?

[jscottsmith]

Love it.

Can you update the README documenting this export. Your usage example would be good to add there too.

Updated the README, check it if everything is fine.
