Support for arbitrary streams for input/output

[slashrsm]

It seems that linefeed currently only supports standard input/output. Goose will accept connections via telnet and expose a command line interface, which allows users to control their load tests. We would like to use linefeed to improve the UX of the said command line, but we would need to be able to wire it into a TCP stream instead of stdin/stdout.

I would like to propose to make it possible to wire linefeed into an arbitrary input/output stream. This approach would allow us to achieve what we want while also opening a lot of other possibilities for the library.

Is this something that would be considered? Are there any plans to do that already?
