Suggestions/Bugs from AMI

Below some comments from @S-Dafarra:

• The starting brightness of the cameras is nearly zero. Hence, when starting everything, the output is nearly all black.
• It would be useful to set some initial parameters that work in a classical lab lighting condition. Moreover, it would be extremely useful to have an "autotune" button.
• The ultrapythonui of https://github.com/robotology/yarp-device-ultrapython is very useful to change the parameters, but it is not complied by default. Plus it has some issues when resizing the window, or when dealing with HighDPI screens.
• The left camera is displayed on the right side of the image, and vice-versa, hence they are swapped. Plus, the images are mirrored.
• One of the eyes, if I remember correctly the left (although I had some doubt since the cameras were swapped), is very out of focus.
• For what concerns resolution and FPS, they are pretty similar to the cameras we currently have on iCub3, since they are at 1280 * 1024@12FPS (on iCub3 we have 1024 * 768@12FPS). Plus the out of focus of one of the eyes, made it difficult to properly asses the image quality.
