coav-control: Visual Debug

[rchiossi]

This patchset integrates vdebug functionality and depth camera visualization into coav-control. It is a compilation of the visualization tool draft implemented my @mbelluzzo and the recent vdebug rework.

This is how it looks like next to gazebo simulation:

About your points:

• fair enough
• yeah, copy/paste from the other branch. =(
• Totally agree! I noticed it was better to have a new header way too late. At that point half the commits changed that header, it would be a nightmare to edit them all. If you don't mind, I'll just create the new header in a new commit.

I agree that we should have a better way to inform what data is expected, but I the old way was a cast nightmare. Any suggestion on how to improve it?

The naming issue sounds fair, but I guess even other depth_cameras returning uint16 might need extra fields not provided. Not sure if just changing the name is a good solution here. Maybe a generic data pointer would be better.

"If you don't mind, I'll just create the new header in a new commit.". Sure.
