Is Futures support planned / in the works?

[phrohdoh]

Returning futures that resolve to tokens / codes / etc. instead of making the HTTP requests internally gives the consuming code more control.

Is this planned?

Alternatively, is this something you'd accept a PR / PRs for?

This was sort of discussed in #22. I don't know the current state of async APIs, but my impression is that they're still more complex than this crate aims to be.
