LordMicrostrainIMU's update method differs in signature

🐛 Bug Report

LordMicrostrainIMU's update method differs from IMUBase. update method is designed to return None, data_packets can be set as a class attribute that the user can access after update is called.

    def update(self, timeout: int = 500, max_packets: int = 1, return_packets: bool = False) -> Optional[list[Any]]:
        """
        Get IMU data from the Lord Microstrain IMU
        """
        data_packets = self._node.getDataPackets(timeout=timeout, maxPackets=max_packets)
        data_points = data_packets[-1].data()
        self._data = {data.channelName(): data.as_float() for data in data_points}

        if return_packets:
            return data_packets
