Is it possible to create a reverse tunnel with this library and if so, could you provide an example?

Thanks a lot for building this library. I'm using it to build a network test at work. Idea is simple:
we need to test lots of ports on target machines from a list of source machines. (20 ports from almost 50 machines).
SSH tunnel(forward) seems like a good idea, because I can do it from the comfort of my local machine
rather than having to write a bash script to source machine.

Here is the issue description:

1. SSH tunnel is created. (port 10022)
2. Did telnet to local port
3. Connection closed on telnet

But it still keeps an ESTABLISHED connection until tunnel is explicitly stopped.
I was expecting this connection to be closed immediately as soon as application exits.

Can I forward a port behind 2 SSH tunnels?

Your library looks great! Might I suggest adding support for Go Modules? Refer here: https://github.com/golang/go/wiki/Modules#how-to-define-a-module

Can we add dynamic port forwarding?

Problem
If a user does not have proper authorization to an SSH host, the sshtun.StateStarted is still being reported as if the connection was successful.

There is no error reported by sshtun and trying to access the forwarded port results in a debug log message similar to "Accepted connection from 127.0.0.1:6753" but the forwarded port never responds.

Expected Result
sshtun should either return an error upon calling sshtun.Start if the authentication is unsuccessful or at the very least not report sshtun.StateStarted.
