Tracking issue: support for SIMD target features #17
Description
Is your feature request related to a problem? Please describe.
We currently support AVX2 only. The goal is to support all SIMD target features. This issue tracks the progress on all of them.
Describe the solution you'd like
Supporting a feature requires changing the SimdBlock and friends to react to a given target feature being enabled and setting the size of the block accordingly.

❌ | #20 | -- | ARM has SVE, which is supposed to be vector-size agnostic, but there's no support for that even in the stdsimd feature. If you need different ARM vector sizes feel free to leave a comment |
