* digital signal: introduce digital signal
* nfca: add nfca signal encoder
* nfc: add mifare classic emulation scene
* nfca: add classic emulation support to lib and hal
* mifare classic: support basic read commands
* nfc: add mifare classic menu scene
* 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
* nfc: format sources
* mifare classic: cleun up
