Fix DQ_CoppeliaSimRobotZMQ class and its derived robots

[ffasilva]

Hi @juanjqo,

The class DQ_CoppeliaSimRobotZMQ had broken references to the DQ_CoppeliaSimInterfaceZMQExperimental class. I fixed them and the references that were also broken on the robots derived from it (FrankaEmikaPandaCoppeliaSimZMQRobot and URXCoppeliaSimZMQRobot).

I just did some preliminary tests on the URXCoppeliaSimZMQRobot, as I'll mostly be inheriting from DQ_CoppeliaSimRobotZMQ to add the dynamic properties, but everything seems to be working now.

Kind regards,
Frederico

Hi @ffasilva,

Thank you for the report. The classes DQ_CoppeliaSimRobot, DQ_CoppeliaSimRobotZMQ, and DQ_CoppeliaSimZmqRobot require modifications to follow the current strategy we adopted concerning a stable and experimental class of the ZMQ interface. In other words, the class DQ_CoppeliaSimRobotZMQ must use the class DQ_CoppeliaSimInterfaceZMQ but not their experimental version. In the last case, we could add a class DQ_CoppeliaSimRobotZMQExperimental.

In summary, we need to remove in a future PR the classes DQ_CoppeliaSimRobot, DQ_CoppeliaSimRobotZMQ, and DQ_CoppeliaSimZmqRobot temporarily.

Kind regards,

Juancho
