Add a reverse connection capability

[skorokithakis]

Most of the time it's not easy to open a port on the host being debugged, e.g. when it's running on a server farm, on CI, etc. It would be great if I can specify a hostname for the debugged program to connect to, rather than from.

Then I could open a listening nc instance at home and the script would connect to me (no need to hang waiting for me).

By the way, if development on this project isn't very active, would you consider adding the project to Code Shelter? It's an open community of FOSS maintainers (please feel free to join!) that aims to help FOSS projects out (fixing bugs, merging PRs, releasing, etc), and I'm a member and can help.

You can read more details about it or add your project to it. There are also people available to help on the Code Shelter chat channel.

Thanks!
