suggest to add support for extended frame (CAN 2.0b)

[kaizh102]

seems current implementation in CanTp doesn't support diagnostic frame with 29-bit identifier.
The parameter "extended" in bus.sent() method inside CanTp class is hard coded to "False".
Suggest to add support for extended frames.

line 47 of .\uds\uds_communications\TransportProtocols\Can\CanConnection.py, "extended=False" makes it impossible to support diagnostics over extended CAN ID.

    def transmit(self, data, reqId, extended=True):
        canMsg = can.Message(arbitration_id=reqId, extended_id=extended)
        canMsg.dlc = 8

        canMsg.data = data

        self.__bus.send(canMsg)
