MIFARE Classic Key Recovery Improvements (#3822)

Browse Source 
* Initial structure for nonce collection
* Nonce logging
* Dictionary attack structure
* Fix compilation
* Identified method to reduce candidate states
* Use EXT_PATH instead of ANY_PATH
* Use median calibrated distance, collect parity bits
* Modify parity collection
* Fixed parity bit collection
* Add note to fix nonce logging
* Fix nonce logging
* Clean redundant code
* Fix valid_nonce
* First attempt disambiguous nonce implementation
* FM11RF08S backdoor detection
* Initial accelerated dictionary attack for weak PRNGs
* Refactor to nested dictionary attack
* Renaming some variables
* Hard PRNG support for accelerated dictionary attack
* Update found keys, initial attempt
* Update found keys, second attempt
* Code cleanup
* Misc bugfixes
* Only use dicts in search_dicts_for_nonce_key if we have them
* Collect nonces again
* Should be detecting both backdoors now
* Relocate backdoor detection
* Hardnested support
* Fix regression for regular nested attack
* Backdoor read
* Backdoor working up to calibration
* Backdoor nested calibration
* Don't recalibrate hard PRNG tags
* Static encrypted nonce collection
* Update TODO
* NFC app UI updates, MVP
* Bump f18 API version (all functions are NFC related)
* Add new backdoor key, fix UI status update carrying over from previous read
* Clear TODO line
* Fix v1/v2 backdoor nonce collection
* Speed up backdoor detection, alert on new backdoor
* Add additional condition to backdoor check
* I'll try freeing memory, that's a good trick!
* Do not enter nested attack if card is already finished
* Do not reset the poller between collected nonces
* Clean up various issues
* Fix Hardnested sector/key type logging
* Add nested_target_key 64 to TODO
* Implement progress bar for upgraded attacks in NFC app
* Typo
* Zero nested_target_key and msb_count on exit
* Note TODO (malloc)
* Dismiss duplicate nonces
* Fix calibration (ensure values are within 3 standard deviations)
* Log static
* No nested dictionary attack re-entry
* Note minor inefficiency
* Uniformly use crypto1_ prefix for symbols in Crypto1 API
* Fix include paths
* Fix include paths cont
* Support CUID dictionary
* Fix log levels
* Avoid storage errors, clean up temporary files
* Handle invalid key candidates
* Fix memory leak in static encrypted attack
* Fix memory leak, use COUNT_OF macro
* Use single call to free FuriString
* Refactor enums to avoid redefinition
* Fix multiple crashes and state machine logic
* Fix inconsistent assignment of known key and known key type/sector
* Backdoor known key logic still needs the current key
* Larger data type for 4K support
* Fix typo
* Fix issue with resume logic
* Mark TODOs for next PR
* Remove redundant assignment
* Fix size_t format specifier
* Simplify auth_passed condition
