Improved TypeScript support

[fabiospampinato]

I'm having troubles typing well this component:

const Scroller = useCallback ( forwardRef ( ( { style, children }, ref ) => {
  return (
    <div style={style} ref={ref}>
      {children}
    </div>
  );
}), [] );

There should be TypeScript types importable from the 'react-virtuoso' package for each of these components Virtuoso accepts, and types for each props object they accept, without them overriding a component and typing it well is way more difficult than it should be.

Agreed, typings are an improvement.
