ARROW-2361: [Rust] Starting point for a native Rust implementation of Arrow This PR implements a subset of data types and array functionality, supporting primitives, strings, and structs. I am actively developing this code and relying on it in my DataFusion project. It isn't fully Arrow compatible yet but I think this is a solid foundation to build from.
