Scheduler Polyfill

This is a polyfill for the Prioritized Task Scheduling
API. Documentation on the API shape
along with examples can be found in the
explainer.

The polyfill includes implementations of Scheduler, exposed through
self.scheduler, as well as TaskController and TaskPriorityChangeEvent
classes.

The implementation uses a combination of setTimeout, MessageChannel, and
requestIdleCallback to implement task scheduling, falling back to setTimeout
when other APIs are not available.

Requirements

A browser that supports ES6 is required for this polyfill.
