Can't build for nightly Rust

Hi Adam,

Your library uses stdsimd as a external dependency crate, which landed in Rust std awhile ago.
It also uses an old target_feature attribute syntax that compiler complains about.
Do you plan on updating your library to compile with nightly Rust any time soon ?
If not, can you please advise me on how to do necessary changes in order to utilize your library,
since I am fairly new to Rust.
