Async implementation

[markedwards]

Is there any interest in an async implementation of this library, probably based on aiohttp? I'm working on porting it for internal use, but would be willing to publish the results here.

Also could do an HTTPX library that provided both sync and async, but at the moment I'm proceeding with aiohttp.

Thanks!

Getting an official async implementation into main would also be nice.
