Some variants of the WS2812 may have their color components in a different physical or logical order. For example, the WS2812B-2020 has physically swapped red and green LEDs, which causes the wrong color to be displayed, because the default order of the bytes sent over the wire is defined as GRB.
In this case, you can change the byte order by defining `WS2812_BYTE_ORDER` as one of the following values:
| Byte order | Known devices |
|-----------------------------------|-------------------------------|
| `WS2812_BYTE_ORDER_GRB` (default) | Most WS2812's, SK6812, SK6805 |
| `WS2812_BYTE_ORDER_RGB` | WS2812B-2020 |
|Byte order |Known devices |
