This fixes the call to the Nextion display to change the pic id from a component.
It was previously changing the attribute `val`, which is related to something else.
In addition, I've changed the parameter for picture_id to be uint_8, as Nextion requires an integer from 0 to 255 on this attribute.
* Add `foreground` color
- Adds `set_component_foreground_color` and `set_component_pressed_foreground_color` which does the same as `set_component_font_color` and `set_component_pressed_font_color` but with a more intuitive name, as this can be used for any component and not only the ones with a text (font).
- I've also reviewed some docstring when related to colors.
* Add numeric color to drawing methods
Should I've used uint32_t instead? In order to keep consistency?
* component color support to uint6_t
This is the right format and is now consistent with colors on drawings.
I'm keeping uint32_t also to avoid breaking changes.
* Enforces uint16_t for colors
uint32_t is incorrect for Nextion display colors.
