lvgl: Missing colorwheel documentation in master branch

In the latest master of LVGL, the colorwheel folder under examples/widgets gone missing. It should be at https://github.com/lvgl/lvgl/tree/master/examples/widgets/colorwheel but it does not exist there.

This causes no Examples and API in the latest documentation of colorwheel in LVGL.

This is the screenshot of the latest documentation on the web:

About this issue

Thank you for sharing. My idea is to allow using an image and specifying the knob movement, such as:

Any: Rectangle image pick any color
Grid: As in your example, allow selecting only fixed positions. If the image is not rectangle we don’t select cells where the opacity is 0.
Circle: Set radius on which the knob can move
Slider: Move vertically or horizontally.
Custom: Somehow allow using custom movement

Once you set the knob somewhere LVGL just ready the color of that image.

What do you think?
