I wanted to look at the code in more detail and it looks like the author didn't link it anywhere. Luckily it wasn't difficult to find:
https://github.com/AdaDoom3/Neo.SIMD
Looks like the author pulled it from his main project (which doesn't look like it's been updated in a while) and at the moment it only supports x86. It's certainly a good start, it could be an easy project to make it an alire crate and publish it.
