Added hf iclass sam --info command that skips any card communication command and just interacts with the SAM to return:
1- Sam Firmware Version
2- Sam Firmware ID
3- Sam Serial Number
Client was expecting a struct starting with an object count but ARM directly sends the array.
The struct is only used on this line in the whole repository, so reverting client is the easiest way to solve the issue.

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.
Updates to the functionality of iclass sim -t 6 to specifically target the last SIO block and to do it automatically.
It now checks the AIA to determine if the card is SR or SE and adjust the block to jam based on the SIO length declared in block 6 (if SE) or fixed length if SR.
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.
Implemented key nibble based multithreading support for hf iclass legbrute.
It takes the whole iclass keyspace based on the first 4 bits of the key value (from 0x0 to 0xF) and divides it across the number of available threads.
E.g. on a 8 threads implementation:
- thread 1 will test keys starting with 0x0 onwards
- thread 2 will test keys starting with 0x2 onwards
- thread 3 will test keys starting with 0x4 onwards
- thread 4 will test keys starting with 0x6 onwards
- thread 5 will test keys starting with 0x8 onwards
- thread 6 will test keys starting with 0xA onwards
- thread 7 will test keys starting with 0xC onwards
- thread 8 will test keys starting with 0XE onwards
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
