Simultaneous file uploads would be cool

Can this be integrated into the library (either using sftp directory) or wrapping an own layer around it which opens multiple instances?

Uploads tend to be super slow...in comparison to i.e. Rsync (which is only allowed if complete SSH access is enabled)

I'll take a look into making it async with a limit - gruntsftp had some similar concurrency restrictions, I'll see if they have since updated their approach.
