Missing polyfill for Promise.allSettled

See original GitHub issue

Now that Promise.allSettled reached stage 4 of the specification process, would it make sense to add a polyfill for it to this project?

Or would you rather recommend to add a separate shim for it, something like es-shims/Promise.allSettled ? IMO that’s less convenient, but creating yet another implementation also sounds wrong.

As a long-time user of this package, it never occured to me that it its features could be scoped to ES2015. I guess it’s because we’ve been using “ES6” as an inaccurate alias for “the time when we got new JavaScript features” for so long.

In any case, other packages I use have started to use allSettled, and they rarely make the destinction between ES levels. They just assume window.Promise is supported with the current promise features. If this package would remain scoped to ES2015, I could no longer use it as an effective IE11 polyfill.
