Clarify implemented Kyber version

[larabr]

I assume this is implementing version 3 (as opposed to e.g. the NIST version), as that's stated by https://github.com/antontutoveanu/crystals-kyber-javascript . But I didn't find specific info about this.
Is the assumption correct? If so, do you have plans to implement the NIST draft version (https://csrc.nist.gov/pubs/fips/203/ipd)?

Your assumption is correct, and I also recognized the need to follow the NIST draft (ML-KEM).
However, I still do not understand the difference between v3 and ML-KEM...

The differences are listed in page 2 of the NIST draft 🙂

FYI I've implemented the ML-KEM changes here, in case you want to apply them to this repo too (I could also open a PR; we still need to maintain a separate fork to support browsers without native BigInts).

@larabr Thanks for your information.

Although I'd like you to send a PR to merge your updates including the support for old browsers here, it is probably a tedious work for you, so I will try to merge them to some extent on my end.
