* nfc: Add NTAG I2C (Plus) 1K/2K read support
* nfc: Add rudimentary NTAG I2C emulation
* nfc: Closer NTAG I2C emulation plus debug logging
* nfc: Fix NTAG I2C sector select emulation
* nfc: Add security for NTAG I2C
* nfc: Send NAK correctly for MFUL reads
* nfc: Better emulate NTAG I2C SECTOR_SELECT behavior
* nfc: Fix non-I2C Ultralight read
Per datasheet, max sector for SECTOR_SELECT is 0xfe, so 0xff is OK
as uninit value
* nfc: Only read sig for NTAG if supported
Attempting to read signature breaks immediate call to sector select on
NTAG I2C original for some reason, so don't read signature if the
command is not supported

1) SubGhz: consciousness and transmission support Security+ 1.0 SAVE AND SEND! ;
2) SubGhz: fix incorrect shutdown of CC1101 if it was not turned on;
3) SubGhz: fix frequency reset on incomplete exit from the transmission menu
Only the bottom nybble of buf[1] is the key ID; the top nybble contains flags.
Notably, the top bit is set for AES mode on EV1+ cards, and ORCA cards in the
Seattle area were just upgraded to include an app that uses AES.
Prior to this, cards with flags set could be read and saved just fine, but
loading them would fail due to missing keys. After this, tags saved with the
old version will load fine, and when re-saved will have the flags separated
out into a new field.
