In go1.21 the go std has a new SHANI accelerated rountine (just like minio's sha256). See golang/go#50543. Reduce the code surface by dropping what is now a redondent librairy. Benchmarks using go1.21 and go1.20 shows no significant difference between minio and the std for sha256: ``` name old time/op new time/op delta SumAllLarge/sha2-256-12 8.63ms ± 3% 8.63ms ± 1% ~ (p=0.220 n=20+17) SumAllLarge/sha2-512-12 23.1ms ± 3% 23.0ms ± 3% ~ (p=0.361 n=18+20) SumAllLarge/dbl-sha2-256-12 36.0ms ± 4% 8.6ms ± 4% -76.16% (p=0.000 n=20+20) name old speed new speed delta SumAllLarge/sha2-256-12 1.94GB/s ± 4% 1.95GB/s ± 1% ~ (p=0.220 n=20+17) SumAllLarge/sha2-512-12 725MB/s ± 3% 729MB/s ± 3% ~ (p=0.350 n=18+20) SumAllLarge/dbl-sha2-256-12 467MB/s ± 4% 1958MB/s ± 4% +319.53% (p=0.000 n=20+20) ``` `dlb-sha2-256` quadrupled in speed because it was never wired to use minio's sha256 implementation and thus was brought back up to speed by `crypto/sha256`'s improvement. I think we should remove `github.com/multiformats/go-multihash/register/miniosha256` one go1.22 is released (~1 year) since it would be purposeless, we could also stub it to github.com/multiformats/go-multihash/register/sha256 for all versions but [no one imports it directly](https://pkg.go.dev/github.com/multiformats/go-multihash/register/miniosha256?tab=importedby).

Go 1.21 improved the performance of `crypto/sha256`. It's now similar to `minio/sha256-simd`, so we should just use the standard libs. https://go.dev/doc/go1.21#crypto/sha256 https://go-review.googlesource.com/c/go/+/408795 multiformats/go-multihash#173
