Feature request: Add the BLAKE3 cryptographic hash

[marknelsonengineer-student]

BLAKE3 was introduced just a few years ago: https://en.wikipedia.org/wiki/BLAKE_(hash_function)#BLAKE3

It appears to be a promising algorithm and I'd like to use it for some research that may turn into an RFC someday.

There's a reference implementation here: https://github.com/BLAKE3-team/BLAKE3

Thank you for implementing Issue #523 and adding BLAKE2.

Blake3 is actively being used by RansomHub C2/python backdoor for decryption and CyberChef is unable to handle it, for example:

data = bytes(a ^ b for a, b in zip(data, blake3.blake3(b'', key=HKDF(b'\xdb\xa3\x8e\x9f\xb6\xb8\xf0\x1f\xb1\xd9\x06\x06\xb2\xfaO\x98O\x9c\xbc\xa4\x80\x12\xfd\xf8\xbd$\tAKF\x1fZ', 32, salt=b'\xecM\xd9m(5\x85z+\xe0\xa0\xa5\xfa\xa6\xbafD\x0035bo\xe8\xb4\xa2r"\xe2pvFc', hashmod=SHA256)).digest(len(data))))
