Implemented an iclass sim function that prevents simulated card responses after updating block 3.
Block 3 gets updated with the XOR key as if it was in personalization mode.
Added an option for hf iclass legrec to further increase speeds by using a shorter delay of 1500 vs the default of 3390.
This seems to be stable on new silicon especially now that we're keeping the field always on.
It may be more risky for the --fast operation.
1- Added a --fast option for hf iclass legrec that further increases the speed from 4.6 key updates/second to 7.4 key updates/second. This is achieved by skipping some safety checks and is a very fast but more risky operation.
2- Automated AA2 block selection based on the values in the config block
3- Other minor code cleanups
Streamlined legbrute to remove then need for CSN and validate variables accuracy as per Iceman's suggestions.
Updated legrec (client side only) for the future arm side PR
Fixed variable overflow on the arm side for hex conversions
