Version 3.0.0

• Use polyfill-library API to generate the polyfill files. Also use dependency resolution from polyfill-library.
• New option excludes do prevent certain dependencies from being included.
• Avoid loading Promise.prototype.finally when Promise is loaded anyways.

Migration from 2.x:

1. Don't change anything.
2. Inspect the generated polyfill file(s). Look at the comment at the beginning to see which dependencies are included.
3. If you see dependencies that you do not care about (e.g. Object.defineProperty which is supported naively from IE 9 onward) then you should add them to the exclude configuration option.
