[FL-2759], [FL-2766] NFC collect params for mfkey32 attack (#1643)

* nfc: start nfc over rpc * nfc: add detect reader state * nfc: add reader analyzer * nfc: rework reader analyzer * reader_analyzer: print collected nonces to debug * reader analyzer: add save on SD card * reader_analyzer: separate mfkey related part to different file * mfkey32: add logic for collecting parameters * nfc: rework pcap with reader analyzer * nfc: add logger for reader * nfc: clean up * nfc: add detect reader view * nfc: add detect reader and mfkey nonces scenes * nfc: add mfkey comlplete scene * nfc: add new assets * nfc: fix gui * nfc: fix iso14443-4 UID emulation * nfc: add no sd card notification * nfc: fix grammar Co-authored-by: あく <alleteam@gmail.com>
