Add P9813 support

[mm-mbs]

Description:

I have added support for P9813 RGB LED controller based on NeoPixelBus.

For use P9813 support you must define the following variables:

#define USE_WS2812
#define USE_WS2812_HARDWARE  NEO_HW_P9813
#define USE_WS2812_CTYPE     NEO_RGB 

Then 2 pins must be configured to P9813 Clock and P9813 Data.

Related issue (if applicable): fixes #8457

@Jaskoxxxx The support for P9813 is not included by default in the Tasmota build. You need to compile your own Tasmota build.
I've done it with TasmoCompiler (https://github.com/benzino77/tasmocompiler). You can read on how to set it up and compile it in that repository.

And as far as I remember all I had to do is to eider check the "WS2812 Leds" checkbox, or in "Custom parameters" add:

#define USE_WS2812
#define USE_WS2812_HARDWARE  NEO_HW_P9813
#define USE_WS2812_CTYPE     NEO_RGB 

Not sure which was the good one. But compile it and you're ready to go.
