Web Extensions polyfill: storage

Web Extensions polyfill for the browser.storage.* API.

The goal with this package is to implmenet a subset of the Web Extensions API that works for Chrome, Firefox, Safari and Edge.

Since this is a subset of the Web Extensions API, not all properties will be available. The best way right now is to look in the index.d.ts which holds TypeScript definitions of the properties available. The interface specificed in the TypeScript definitions should work on all platforms.

PRs welcome 🚀
