Adding Rust world

Hi, I've worked on a Rust world version of the Jargon project recently as a side project.

I think the Rust variation will be an interesting addition to the Functional Programming Jargon projects family for the following reasons
- Rust is gaining a lot of tractions
- Although it may seem like it supports functional programming features, it does not have Higher Kinded Type, currying, auto-currying and subtyping. functional-programming-jargon.rs provides workarounds to these problems
- An attempt to emulate the Haskell ecosystem in a system-level programming language
