Suggestion/Bugs from EDPR

[triccyx]

Some points came from EDPR @Iaxama:

• Keep Exposition range between 15msec to 50msec
• Bug on white balance, Red should be switched to Blue.
• Check for artifacts in HiRes again
• Log absolute exposition info
• Add the third channel for white balance via rpc API
• Check for latency
• Left cam on setup is not perfectly on focus
• preview is missing in UI
• subsampling info is missing in UI
• test honorfps from UI is working as expected?
• application ico is missing
• add contrast control
• Reconnect button in UI
• Add example for a client
• Split README.md
• Allow set also with absolute value from API
• Log temperature on UI
• UI window should not be resizable
• Fill help
• Default value button on UI
• Led on UI for signal if the board is working

Log absolute exposition info, for now, could be done only on the yarpdev log together with the statistics I have added. See above,

[INFO] |yarp.device.usbCamera| frames read by YARP  frame number: 66  fps: 13.2  interval: 5.02771  sec.  exposition: 15  msec.
[INFO] |yarp.dev.Drivers| device active in background...

@salvi-mattia "Left cam on setup is not perfectly on focus." If you are at CRIS on the 12th or 13th could you check it with me?

Relating to latency:
I have reduced the number of buffers submitted to the low-level driver and the latency is now ok.
Note: Some other tests needed
Thanks to @Iaxama for having spotted the problem.
