docs: Protect a FeliCa Lite Tag.
  
          A FeliCa Lite Tag can be provisioned with a custom password
          (or the default manufacturer key if the password is an empty
          string or bytearray) to ensure that data retrieved by future
          read operations, after authentication, is genuine. Read
          protection is not supported.
  
          A non-empty *password* must provide at least 128 bit key
          material, in other words it must be a string or bytearray of
          length 16 or more.
  
          The memory unit for the value of *protect_from* is 16 byte,
          thus with ``protect_from=2`` bytes 0 to 31 are not protected.
          If *protect_from* is zero (the default value) and the Tag has
          valid NDEF management data, the NDEF RW Flag is set to read
          only.
