Support planned for apple silicon?

It looks like the current implementation only supports x86: https://github.com/janestreet/ocaml_simd/blob/d35a00dcdcb642c2f1fa0e47b0749ebb7fe11af6/avx/avx_stubs.c#L33-L36

Are there any plans in the works to support apple silicon?

Start with avx/avx_stubs.c at the referenced lines to understand the current x86-only implementation and inspect the surrounding SIMD support. The issue does not define the Apple Silicon scope, implementation approach, or acceptance criteria, so the work is not ready to begin without clarifying what support and validation are required.
