New: implementing hf mf hardnested

This implements the attack described in
	Carlo Meijer, Roel Verdult, "Ciphertext-only Cryptanalysis on Hardened
	Mifare Classic Cards" in Proceedings of the 22nd ACM SIGSAC Conference on
	Computer and Communications Security, 2015
It uses precomputed tables for many bitflip properties (not only two as in the paper)
and is therefore quite efficient. To prevent failing it doesn't do
differential analysis with several nonce bytes' Sum(a8) properties (each of them
may be wrongly guessed) - instead it concentrates on one nonce byte and tries all
Sum(a8) property guesses sequentially (ordered by probability). The brute force phase
makes use of aczid's bit sliced brute forcer (https://github.com/aczid/crypto1_bs).
Includes runtime CPU-detection to leverage modern (and old) SIMD instructions
with a single executable.
