Support reversed order data stream

[Makuna]

Is your feature request related to a problem? Please describe.
The order for the pixels is reversed on some LEDs, the last pixel is sent first.

Describe the solution you'd like
Maybe part of the buffer redesign, but either the feature or the method needs a way to support that pixels are in reverse order.

Describe alternatives you've considered
Leave it alone, as the experience is just that the first pixel is at the other end of the strip, it is just a perception issue.
