Improvement: change from 0-1 to 0-255 RGB colours

[cue-td]

Could it be considered to change from the current 0-1 to the more standard 0-255 scale for RGB colours?
This would make choosing a specific colour from an RGB Color Chart far more trivial than converting.
i've purposely picked a weird colour here as an example: For a light green, this would be R102,G255,B102. and i could then scale those numbers for brightness. I could simply type these numbers in to the config. While is is trivial to convert, i now have to convert to a 0-1 scale potentially multiple times per colour.

This could further be inproved upon with an addition of a seperate 'brightness:' state where i can statically define a colour (eg R255 G0 B0) and setting brightness to 0.5 would automatically change all defined RGB values in the [led_effect].

Using the idle example from the docs, this is how i'd envisage it would work. the result would be 'light shade of blue' at 50% brightness.

[led_effect panel_idle]
autostart:              true
frame_rate:             24
brightness:  0.5
leds:
    neopixel:panel_ring
layers:
    breathing  10 1 top (128,128,255)

Colors from 0 to 1 is the Klipper way to define colors. But I was already thinking about supporting something like (#12FFAB). So it's on the backlog. Adding brightness is also possible, but I was thinking of making it a parameter for SET_LED_EFFECT.
