ADD IPs control interface for robot connection in neuronavigation

[MarcioCamposJr]

I changed the preferences page to make it possible to add and remove robot connection IPs to make the neuronavigation routine easier.

Thanks for the PR @MarcioCamposJr!
I got the following error after delete the init IP, close it and open it again. I suggest to always load the ROBOT_IPS from constants.py

\invesalius3\invesalius\gui\preferences.py", line 1590, in init
choice_IP.SetSelection(robot_ip_options.index(self.robot.robot_ip))
