Deprecate library? about num_cpus

[SUPERCILEX]

Interesting, looks like there's a PR to fix that: rust-lang/rust#92697. In the meantime, perhaps it's worth pointing out the differences?

update: the mentioned PR is now merged

Either way, I feel like the important thing is that this crate is available on earlier versions of Rust, which is important to crates who don't want to bump their MSRV.

Take a look at the limitations section on that function. This crate does check processor affinity, and cgroups, and doing so has an important impact on servers running in containers.

Here async-global-executor crate switched to the standard API: async-rs/async-global-executor#6

Here rayon crate is considering dropping the library: rayon-rs/rayon#937

Yea, probably not going to do this just yet.
