Feature/other args

[kylewhite21]

Small change to allow more args to connect/1. I specifically needed to supply a ssh key passphrase. I also moved host and port to new args.

I haven't changed any docs or the README. I can make those edits if you want to pull this in.

Thanks for the PR! Unrelated question, have you checked if your use case can be covered by using https://www.erlang.org/doc/man/ssh#tcpip_tunnel_to_server-5 (available since OTP-23)? That might be a more stanzdardized way of doing it. When I wrote this lib, that functionality was not yet in OTP.

Hmm that function does seem to be exactly what I need. I'll have to try it out shortly. Thanks for pointing it out!

Thanks for the hint, that function is exactly what I needed. It's simplified a lot of things. But thanks for having this code to get me off the ground!
