requestIdleCallback polyfill

Simple polyfill and d.ts for
requestIdleCallback.

From MDN:

> The window.requestIdleCallback() method queues a function to be called during a browser's idle periods.
> This enables developers to perform background and low priority work on the main event loop, without
> impacting latency-critical events such as animation and input response. Functions are generally called in
> first-in-first-out order; however, callbacks which have a timeout specified may be called out-of-order if
> necessary in order to run them before the timeout elapses.

> You can call requestIdleCallback() within an idle callback function to schedule another callback to take
> place no sooner than the next pass through the event loop.

npm i requestidlecallback-polyfill

yarn add requestidlecallback-polyfill

import 'requestidlecallback-polyfill';
