Rust-Cast-Shootout

Learning how to cast a Float into a u8. See the Reddit thread for more information.

The original implementation was written by me for use in Rust-Trace. The min/max approach was suggested by arthurprs and he also genericised the original implementation. The iterator based approach was suggested by thiez.
