fearless_simd takes unsafe out of SIMD.

No matter what level of abstraction you're after, be it autovectorization and multiversioning, or portable SIMD, or safe access to raw intrinsics and nothing more, fearless_simd has you covered!

Just adding some context. Seems like the v1 announcement, which is cool. It looks like a really useful crate, and I'm sure I've used it transitively at least once (based on the download count), though not directly yet.
