Support for RGBIC + CCTIC ledstrips like LCS 3203632.1

[twoenter]

Describe the problem you have/What new integration you would like

1. Support for separate CW/WW IC chips in beken_spi_led_strip besides RGB so CW/WW LEDs don’t need to be controlled with red and green.
2. Support for arrays of LED numbers, allowing you to create segments like 0, 2, 4, 6, 8, etc., and 1, 3, 5, 7, 9, etc., to set colors or white values properly across multiple segments.

Please describe your use case for this integration and alternatives you've tried:
Using light partitions, I can test the correct colors and white values for separate segments. RGB LEDs work as expected, but for white values, you must select Red for Cool White and Green for Warm White in the color picker.
