Proxy events

[szmarczak]

I forgot to remove the aborted event proxy from my previous PR. The docs were a bit misleading. I've fixed it via placing toStream.destroy() before emitting the aborted event. Also fixed the docs.

Also added proxy for the close event.

I think this is a minor change (3.1.0) 😅

The only limitation after this PR is to implement the destroy() function: #6 (comment)

But people should do it on their own as replacing stream._destroy is ugly, not safe and people need to pass {autoDestroy: false} anyway.

This is failing on Node.js 12.

Fixed :)
