* mifare classic: start parsing commands in emulation
* mifare classic: add nested auth
* nfc: fix errors
* mifare classic: add encrypt function
* nfc: fix mifare classic save
* lib hex: add hex uint64_t ASCII parser
* flipper format: add uint64 hex format support
* nfc: add mifare classic key map
* nfc: hide mifare classic keys on emulation
* mifare classic: add NACK responce
* nfc: add partial bytes support in transparent mode
* nfc: mifare classic add shadow file support
* digital signal: move arr buffer from BSS to heap
* mifare classic: process access bits more careful
* nfca: fix memory leack
