Multiversion in lieu of compiling from source with RUSTFLAGS="-C target-cpu=native"

I was wondering if you are open to uitilizing the multiversion crate to utilize dyanamic dispatch, rather than having users compile from source (to get the best performance).

I use multiversion for my own project and it's great! You can see example usage here.

I can run a before/after benchmark using your existing benchmarks to check for any regressions.

Thank you!

Yes, multiversion seems like the way to go. Do you want implement it?

@LaihoE

I'll start on a PR for this issue once the benchmarks PR is sorted out. That way, I can easily establish a baseline to test for regressions. Thank you!!

Sorry if you were working on this, It is just blocking some future ideas with SIMD_LEN, so I went ahead and added multiversioning.
