Use of the python3 branch and the CEF codec results in the following error:

TypeError: a bytes-like object is required, not 'int'
Python2 handled the conversion to bytes when using struct.unpack, Python3 does not.
Can be resolved by updating line to include bytes conversion:
byte = struct.unpack( '>B', bytes(self.data[byteIndex]) )[0]
