When querying a BINARY/VARBINARY/LONG VARBINARY type value, data sent by server is the text representation of octal bytes.

For a \xxx octal byte, text representation is 4 bytes. E.g. \341 gives bytes(['\\', '3', '4', '1']).
For an escaped \, text representation is 2 bytes. E.g. \\ gives bytes(['\\', '\\']).
For an ASCII character, it is the same as its text representation.

This fix parses the raw data from server and convert it back to binary.
