replace crypto/sha256 with github.com/minio/sha256-simd

[yeya24]

Is your proposal related to a problem?

Currently crypto/sha256 is mainly used for calculating hash of files we upload/download to/from the object store.
As shown from https://github.com/minio/sha256-simd, the performance is much better than crypto/sha256 in golang.

Describe the solution you'd like

Simply replace the library.

Additional context

Thanks for the feedback @yeya24 . I've fixed the import grouping you mentioned. However, I'm not sure how to verify this:

I guess you'd have to try and build an image for one of the mentioned unsupported archs:
