Support Different Vector Instructions

[ruler501]

Using something like the eve library could work well to allow writing code that works on different architectures. I'm specifically interested in an SSE4.1 or AVX implementation.

I could probably look into working on this sometime next month if I have time.

Hi @ruler501. Supporting different vector instructions would be great. I'm personally not sure what the use case would be for pre-AVX2 x86 instructions, since AVX2 has been out since 2013, but I'm sure you know your application better than I do.

I'm pretty bandwidth-limited these days, but happy to provide high-level guidance if I can be helpful.
