Incorrect Parsing of Extra Data(NDB info) in Rows Event

[chungeun-choi]

The following is the code for parsing rows events within the Rows Event. It was observed that the nbd_info_length and nbd_info_format should each be read as 1-byte values, so they need to be modified to self.packet.read(2).

  python-mysql-replication/pymysqlreplication/row_event.py

  Line 65 in c977dd8

  self.nbd_info_length, self.nbd_info_format = struct.unpack('<BB', self.packet.read(1))

• The table below is derived from comments in the MySQL source code, describing the format of extra data (NDB info):

   	+----------+--------------------------------------+
          |type_code |        extra_row_ndb_info            |
          +--- ------+--------------------------------------+
          | NDB      |Len of ndb_info |Format |ndb_data     |
          | 1 byte   |1 byte          |1 byte |len - 2 byte |
          +----------+----------------+-------+-------------+
