Currently we are using the pure rust backend of `sha2`, which has subpar
performance compared to asm implementations. We already depend on
`ring`, so just use that instead of `sha2` for sha256/sha512 digests.
This also speeds up things like S3 uploads, which calculate sha digests
of the uploaded objects. On my local machine, this speeds up uploading a
100MB file (to a localhost s3 provider via`@aws-sdk/client-s3`) by about
2x
