Rust bindings: add typical impls about blst

However I suspect that you might know faster or more elegant ways to achieve these things.

Don't be so sure:-) PR is welcomed!

I wonder what the best practice is, e.g. RustCrypto's signatures crates have explicit PartialEq impl for their dsa and ecdsa crates.

Formally speaking this is not exactly a right place to pop such a question. As we are not considering ourselves as a "Rust shop." We do exercise, and one might even say advocate for minimally-required principle though. Taking this question as an example. You are not supposed to use your secret key for anything but signing, so why would it require a comparison trait? One can make a legitimate case against attaching generic traits as they make no commitments to constant-time execution, while blst does...
