Specify "524,288" iterations instead of "500,000"

CryptoNight does exactly 524,288 iterations over the scratchpad as defined in CNS008, saying 500,000 could be confusing. I know its meant to give a rough idea (around 500k) to the reader but if you are reading the code, might as well know the exact number.
