Is your feature request related to a problem? Please describe.
I'd like to use wstunnel as a library. Essentially having some agents register with a server (currently just forwarding a unix socket, so for this I can use the CLI ) and on the server-side, re-exposing the connected clients again as unix sockets, and/or providing some listing (for this I'd need to write some custom code).

Describe the solution you'd like
Expose parts of wstunnel as a library, so I can use reuse the client and protocol

Describe alternatives you've considered
Adding more features into wstunnel directly.
