Calculate a 512-bit hash of 'input' using 4 lanes of AES.
The input is treated as a set of round keys for the encryption
of the initial state.
'inputSize' must be a multiple of 64.
For a 2 MiB input, this has the same security as 32768-round
AES encryption.
Hashing throughput: >20 GiB/s per CPU core with hardware AES
