Implemented Rust bindings.

[Techcable]

Hi! I implemented safe Rust bindings to this library as the utf8proc crate.

I reimplemented the utf8proc_map function to support reusing allocations and to use the Rust allocator instead of malloc.

You may want to consider adding this to the readme so that people can find it.

Thanks! I linked this from the README in 20d192a

Right, this is what Julia does as well — you want to call the lower level utf8proc_decompose and utf8proc_reencode functions directly if you want to have more control over allocations. See also #101 (comment)
