Rework of 'hf iclass snoop', including jamming option

For those who are interested in iClass research: with PR#884 on official repository comes a working 'hf iclass snoop'.

As a bonus it has an option to jam (prevent) CC updates. If you don't know the advantages of an unchanged CC then this is not for you smile.

Hint: snooping works best with the antenna directly "attached" to the card and positioned between card and reader. Use the B and C LEDs to find the best snooping distance.

I have added an '-n' option to 'hf iclass readbl' and 'hf iclass dump' for replaying a NR/MAC pair gathered with 'hf iclass snoop --jam'. Enjoy.

Depends. Snooping and replaying NR/MAC should work on every Picopass card. Which doesn't mean that you can create working clones of each and every card.
