style: Remove bindings.rs.

I kept it building the most straight-forward way possible (pub use) because it
seems to me that bindings is not a bad name, and we should probably move
structs.rs to be bindings.rs rather than the other way around.

But that's a different bug in any case, need to think more about it.
