Pre-generated FFI bindings

[emoon]

Hi,

First of all thanks for a great crate :)

I wonder if it would be possible to change this crate to include a pre-generated file of the Rust bindings made in this code https://github.com/koraa/xxhrs/blob/master/build.rs#L32-L42 ?

The reason I'm asking for this is that the dependency on bindgen adds quite a bit of extra compile time as it depends on clang which is quite heavy dependency wise.

Sure! Would you mind creating a pull request?
