Rust/Windows Support

[alexipeck]

What work needs to be done for the Rust version?
The Rust crate hasn't been updated in 2 years and currently doesn't compile under Windows.

The following error output is the main culprit preventing compilation under Windows, this particular issue is likely from the proc-macro-crate and was fixed in version 1.2.1 (rust-lang/rust#94913)
"thread 'main' panicked at '"zts_net_info_t_struct_(unnamed_at_src/include/ZeroTierSockets_h_816_5)" is not a valid Ident', C:\Users\alexi.cargo\registry\src\github.com-1ecc6299db9ec823\proc-macro2-1.0.52\src\fallback.rs:752:9"

If a public repo for the Rust crate became available, I would be like to assist in maintaining it and fully integrate this into another project.
