Windows validation action still failing about py-ipv8 HOT 3 CLOSED

As far as I can see, we can't substitute libnacl with cryptography easily. The former uses Salsa20 to implement crypto_box_beforenm (ref) and cryptography doesn't seem to support Salsa20. The alternative would be to reconstruct Salsa20 from the ground up and that seems unworkable and impractical for a simple workaround.

The only real alternative is to then simply skip tests related to the tunnel crypto.

Another option would be to bring back NoTunnelCrypto when libnacl is not found while testing.

I've been convinced that installing the libsodium backend on the Windows testers is the only way for our validation test matrix to make sense. Workarounds seem to be too elaborate or (more generally) too error-prone and not testing the tunnels would casually ignore one of the integral parts of IPv8. We'll just have to bite the bullet and perform the GitHub Actions setup.
