FIX: Forget that the prng was 0x8000 length and not 0xFFFF. Sorry. Also returned...

CHG: returned the iso14443a_setup order, it might influence my older PM3 device.

*Note*  my Elechouse revisions PM3 works great with this but my older xpfga (green pcb) is hopeless.  It can't fix onto the nonces in 'hf mf mifare'  I think its too slow.
