Initial import from pq-crystals/kyber/ref @ 11d00ff1

[jschanck]

This is a straight copy of the ref/ subdirectory from pq-crystals/kyber @ 11d00ff1.

Is this what we want?

Some initial thoughts.

• We may want to move test/ and nistkat/ out of src/.
• Consumers of this probably have their own build systems, so maybe the Makefile needs to move as well.

Great, thanks for this initial import!

In OQS we currently import the "standard" branch from pq-crystals and apply a few patches along with the import. May it be worth adding parts of the patch to this repo (e.g., to simplify import to OQS)?

The patches are:

• Updating the meta.yml files (Name: ML-KEM-(ipd), correct KAT and test vector hashes)
• Updates the KYBER_NAMESPACE macro
• Integrate with the SHAKE incremental API in oqs

The commit needs updating with

git commit --amend --no-edit --signoff

to accept the DCO

Perhaps both @jschanck 's suggestion re: test, and @bhess 's suggestion for integrating some patches to better facilitate later merge, could be raised as distinct issues? (I'd be happy to help out with these or raise those issues if it helps)

DCO needs accepting (see comments)
