bevy_color: Added Xyza Colour Space (#12079)
# Objective Add XYZ colour space. This will be most useful as a conversion step when working with other (more common) colour spaces. See [Wikipedia](https://en.wikipedia.org/wiki/CIE_1931_color_space) for details on this space. ## Solution - Added `Xyza` to `Color` and as its own type. --- ## Changelog - Added `Xyza` type. - Added `Color::Xyza` variant. ## Migration Guide - `Color` enum now has an additional member, `Xyza`. Convert it to any other type to handle this case in match statements.
