Hi,
thank you for providing the decoder for the WS281x protocol.
As there are now not only RGB but also RGBW stripes commonly available I
would propose a small improvement: Add an option to switch between 3 and 4
bytes.
The change is pretty trivial and straightforward.
Hope this helps & best regards
Sam
