OK, Yes, I will look into that.

Oops! Sorry that I missed that.  I looked onto that and argon2 bundles
blake2.  I am working on patches for the two of those right now.

Ah, OK.  I just looked at their README which just says GPL3.  I will
change that.

I am planning to submit a new patch after argon2 + blake2.  Hopefully
