Add the Rust crate: rzpipe.rs

[officialcjunior]

Detailed Description

This is a basic implementation rzpipe.rs. This is basically r2pipe.rs with the struct variables and such changed.

There's a lot of other things I was unsure about, like the CI configuration files, copyright and licenses the r2pipe had, so I have kept those as it is. I'm hoping to resolve all of that here, along with the changes in the code, if needed.

Test plan

I had tested every examples in the examples directory and it works, I'll attach screenshots of them if necessary. I'm not an expert on Rust too, so please request changes.

What to do Authors on the Cargo.toml and the copyright files?

[XVilka]

Those should be preserved as is.

Great. Are we planning to publish this as a crate at crates.io?
