Noise support as alternative to TLS

[Nuhvi]

Supporting Noise encryption instead of TLS reduces reliance on DNS and is faster than TLS which is useful for mobile applications (not available to browsers though).

To do so, we need:

1. Get server's public IP (from user or Mainline).
2. Adapt Axum to user Noise somehow! (keep an eye on https://github.com/dignifiedquire/nquinn)
3. Adapt Ureq to support Noise somehow.

Consider using custom rustls certificates verifier instead.

we are going to use TLS over Pkarr in #37
