Switch to rustix?

[SUPERCILEX]

https://github.com/bytecodealliance/rustix is probably the future of safe libc in rust, so it'd be nice to have this crate use it instead of nix so consuming crates end up with fewer dependencies. For example rustix is indirectly used in clap through terminal_size.

Could be done in a new major version.

ctrlc uses signal::sigaction, but this functionality is intentionally not implemented in rustix (see: bytecodealliance/rustix#628).

It does exist in c-scape, but that's libc oriented.

I'm not sure if you can really leverage c-scape for that unless intentionally replacing the libc for a program... in which case it'd not be something for a library crate to support, but up to the developer to choose using something like eyra in their application's Cargo.toml?
