Erase the NDEF message on a Type 2 Tag.

        The :meth:`format` method will reset the length of the NDEF
        message on a type 2 tag to zero, thus the tag will appear to
        be empty. Additionally, if the *wipe* argument is set to some
        integer then :meth:`format` will overwrite all user date that
        follows the NDEF message TLV with that integer (mod 256). If
        an NDEF message TLV is not present it will be created with a
        length of zero.

        Despite it's name, the :meth:`format` method can not format a
        blank tag to make it NDEF compatible. This is because the user
        data are of a type 2 tag can not be safely determined, also
        reading all memory pages until an error response yields only
        the total memory size which includes an undetermined number of
        special pages at the end of memory.

        It is also not possible to change the NDEF mapping version,
        located in a one-time-programmable area of the tag memory.
