FIX:  'hf mf mifare'  - special zero parity attack vector now works. Thanks to the dude who figured this vector out: @douniwan5788  (sorry for comments, I was clearly wrong.)  @piwi - for proving me wrong.
this version uses int64_t  (signed)  to signify end-of-lists (-1). It also needs its own compare function for the qsort.  I didn't merge this into existing code which uses uint64_t. (too lazy)
