Perform PUF registration on a Spartan UltraScale+ device and write the result to a JSON file. The output JSON contains the AES-encrypted black key (the red key encrypted using the internal PUF KEK and user-supplied IV), along with PUF helper data (pufhd), PUF hash, and related fields. The PUF KEK is an internal device secret and is never exported from the device. Replaces the deprecated generate_puf_kek command.
