We search for ST25TB type cards, but not handling them being found.
As a result, such cards are detected as NFC-A with 8-byte UID, which lead
to read error on emulation attempt.

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
