* improve digital_signal for longer packets, also clean up code * added SLIX2 specific features like signature and unknown keys (for issue #2781), added WRITE_PASSWORD handling * fix NfcV AFI selection * when NFCV_CMD_READ_MULTI_BLOCK reads beyond memory end, return the maximum possible block's content * added SLIX2 reading * fix NXP SYSTEMINFO response check size * capture the first received password if none was set before * clear stored data before reading SLIX details renamed slix2_dump functions to slix2_read * display card block size values as decimal Co-authored-by: あく <alleteam@gmail.com>
