impl fmt::Display for NetAddress

[benthecarman]

tried to do this one myself but don't really know how the tor addresses are meant to be displayed.

ChatGPT gave me this but it's really ugly so didn't want to commit it

use core::fmt;

impl fmt::Display for NetAddress {
    fn fmt(&self, f: &mut fmt::Formatter<'_>) -> fmt::Result {
        match self {
            NetAddress::IPv4 { addr, port } => {
                write!(
                    f,
                    "{}.{}.{}.{}:{}",
                    addr[0], addr[1], addr[2], addr[3], port
                )
            }
            NetAddress::IPv6 { addr, port } => {
                write!(
                    f,
                    "{:02x}{:02x}:{:02x}{:02x}:{:02x}{:02x}:{:02x}{:02x}:{:02x}{:02x}:{:02x}{:02x}:{:02x}{:02x}:{:02x}{:02x}:{:02x}{:02x}:%{}",
                    addr[0], addr[1], addr[2], addr[3], addr[4], addr[5], addr[6], addr[7],
                    addr[8], addr[9], addr[10], addr[11], addr[12], addr[13], addr[14], addr[15],
                    port
                )
            }
            NetAddress::OnionV2(addr) => {
                let mut onion = [0u8; 12];
                onion.copy_from_slice(addr);
                let mut base32 = String::new();
                // Implement your base32 encoding function here
                write!(f, "{}.onion", base32)
            }
            NetAddress::OnionV3 { ed25519_pubkey, checksum, version, port } => {
                // Implement your base32 encoding function here
                let mut onion = String::new();
                write!(f, "{}.onion:{}", onion, port)
            }
            NetAddress::Hostname { hostname, port } => {
                write!(f, "{}:{}", hostname, port)
            }
        }
    }
}

Lol. After #2134 we'll have "implemented your own base32 encoding function here" we can reuse :).
