Hickory-DNS: a Rust based DNS client, server, and resolver

> Hickory DNS will work to support backward compatibility with three Rust versions.

Is this something many Rust projects do? We are at 1.93 now and 1.90 is from september 2025. The Rust community is crazy if they think this is normal. This is for DNS a stable component of the system.

Depends on Tokio crapware :( This is crazy for a systems programming library
