consider switching to run-auto?

This library only ever uses async.auto yet pulls in all of the async library (thus bloating webpack and browserify) builds.

Thoughts on moving to just using the run-auto lib (used by webtorrent)?

I know that if we do this it will probably mean that a lot of other code/libs needs to switch to using run-auto, run-parallel, and run-series

We could also always wait until async offers modularized exports.

sounds good to me 👍
