refactor(users/edef/refscan): switch to intrinsics r/5637
packed_simd is deprecated, but we don't need very much SIMD:
  * _mm256_set1_epi8 / vpbroadcastb (splat)
  * _mm256_cmpgt_epi8 / vpcmpgtb (comparison)
  * _mm256_movemask_epi8 / vpmovmskb (compress to bitmask)

This also simplifies the code by only vectorising the bare minimum,
since we just get a bitmask and operate in scalar mode as soon as
possible.

We don't need nightly Rust anymore: we're using only stable intrinsics.
