KinematicUnitCore: Implement the methods used in the JointUpdateReceiver to send data updates

The methods should modify data in the self.joints dictionary

Implement the following methods in the KinematicUnitCore:

    def update_joint_angle(self,
        name: str,
        angle: float,
    ) -> None:

    def update_joint_velocity(self,
        name: str,
        velocity: float,
    ) -> None:

    def update_joint_torque(self,
        name: str,
        torque: float,
    ) -> None:

    def update_joint_acceleration(self,
        name: str,
        acceleration: float,
    ) -> None:

    def update_joint_current(self,
        name: str,
        current: float,
    ) -> None:

    def update_joint_motor_temperature(self,
        name: str,
        temperature: float,
    ) -> None:
