NeoPixelBus add new color order - Cold - Warm White

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

I intend to add support for a NeoPixelBus color order (parameter `type`) CWWW for an SPI LED strip that has CW (Cold White) on the first channel and WW (Warm White) on the second. While I can typically control the LED strip using any color order, the strip only has two colors, not three, so the last channel is always unused.

**Please describe your use case for this integration and alternatives you've tried:**

I tried to use templates for a fix color order but I wont find any suitable solution.

**Additional context**

Used led strip: [https://www.aliexpress.com/item/1005005069644213.html](https://www.aliexpress.com/item/1005005069644213.html)

Start by locating the NeoPixelBus color-order definitions and the SPI LED-strip entry point that accepts the `type` parameter. Compare existing orders with the requested CWWW layout; done means a two-channel strip can use Cold White and Warm White without requiring a third channel.
