Check whether a password hash appears in the Have I Been Pwned breach corpus using k-anonymity: the caller sends only the first five hex characters of a SHA-1 hash, so no password or full hash ever leaves the caller. Returns the matching hash range, or a breach count when an optional suffix is supplied.
