Update the LinuxLEDController to support multicolor LEDs defined by
the Linux kernel. For multicolor LEDs Linux exposes a single
brightness which allows a range of 0 (off) to 255 (max) and a multi_intensity
value that accepts multiple channels of colors. This current implementation
assumes that there are 3 multi_intensity channels between 0 and 255.
https://docs.kernel.org/leds/leds-class-multicolor.html
Note that for now in Linux the brightness value doesn't so much affect
the brightness of the LED as it does apply a coefficient to the individual
channel intensities. For now hard code the brightness to 255 and simply
adjust the intensities to alter the color.
This change should keep the existing sysfs code path as-is and only attempt
to use this new method when a led_rgb_path is present in the config file.
For reference, my OpenRGB.json has the following lines:
` "LinuxLEDDevices" : {
"devices": [
{
"name": "Fan LED 1",
"rgb_path": "/sys/class/leds/rgb:programming-0/"
}
]
}`
