Proper Crypto for remote connections

[Nukesor]

For now, pueue only supports tcp connections via localhost.

async-tls looks quite promising.
However, we need a way to create new server and client certificates, if they're missing.
I'm still looking for a nice way to do this inside of pueue. I don't want to rely on external (system-specific) libraries and binaries.

Remote connections shouldn't be handled with ssh pair keys?

Well, one can use SSH tunnels/port-forwarding for now in combination with Pueue.
However, this is a little cumbersome. Integrating tools with the SSH protocol also tends to be quite annoying.

Simple TLS crypto with a proper Authentication via Client-Certificates seems like a good mix between security and convenience.
