draft for a Mifare classic NACK bug detection.

Browse Source 
the idea is to have a statistically solid conclusion if tag does or does not have the NACK bug.

-in short, ref  https://github.com/iceman1001/proxmark3/issues/141
NACK bug;  when a tag responds with a NACK to a 8 byte nonce exchange during authentication when the bytes are wrong but the parity bits are correct.

This is a strong oracle which is used in the darkside attack.
