It would be useful to add avx-512 optimizations for the resampler in an independent file

@Luni-4 do you have hardware capable of running avx512?

I can test for you, the machine is really noisy so I cannot keep it up all the time

so far avx512 is in experimental state and some basic intrinsics arent in core::arch::x86_64 platform module (for example loadu_ps and setzero_ps)

just found
https://github.com/rust-lang/stdarch/blob/a3710694f94f13758799996e981dd2cc1069a514/crates/core_arch/src/x86_64/avx512f.rs#L91-L93
it seems just the docs are outdated
😌

UPD: oh, there is no _mm512_loadu_ps 😢

I guess we just wait for avx-512 to be stabilized then
