sha3: add support for Keccak-512

Keccak uses a different domain separation byte as the NIST-
standardized SHA-3 hashing function. A previous commit to
this package added support for Keccak-256, but did not do
so for Keccak-512. The reasoning was to support use cases
like Ethereum, however Ethereum also uses Keccak-512 for
the Ethash PoW, so this second method is also needed.
