Support for ws2814 32 bit Addressable LED (bk72xx) (Beken SPI LED Strip)

[postal302]

Describe the problem you have/What new integration you would like Add support for for WS2814 Addressable LEDs to the Beken SPI LED Strip platform https://esphome.io/components/light/beken_spi_led_strip.html for use with Beken bk72xx chips.

Please describe your use case for this integration and alternatives you've tried: New smart addressable LEDs are shipping with beken chips. I have a set of Ligency outdoor spotlights https://a.co/d/io0m6lA that use a CBU WiFI module (bk7231n), but there is virtually no support for beken chips and addressable LEDs with 32 bit data packets. I've set the Beken SPI LED Strip platform for ws2812 and it lights the spotlights and changes colors, but the colors are random and not all lights work. None of the other built in LED chipsets work for this either.

Here's the datasheet for the ws2814 https://www.superlightingled.com/PDF/SPEC/WS2814-RGBW-Datasheet.pdf

Additional context There are other features/issues that use the ws2811 settings to successfully control the ws2814 (see here: https://github.com/esphome/feature-requests/issues/2049) but that only works for ESP chips and not Beken chips. I've also installed OpenBeken on the CBU and it does not yet support ws2814. https://www.elektroda.com/rtvforum/topic4028972.html

It is understood that the WS2814 is a variant of the SK6812 with a W channel: https://wled.discourse.group/t/are-ws2814-24v-rgbw-led-strips-compatible-with-wled/5601/28

A workaround for using the Beken_SPI_LED_Strip platform is to use the sk6812 chipset and set "is_wrgb" to true. I also had to set "rgb_order" to RGB because the default GRB was incorrect. After this the lights are showing the correct color on all pixels and have white as a color option. Finally, using "- platform: partition" allows individual control of each addressable pixel.

Here's my yaml for my 4-spotlight setup:
