`Okhsl` and `Okhsv` support for bevy_color

[realhackcraft]

What problem does this solve or what need does it fill?

Okhsl is better than oklch at randomly generating hues while keeping other conditions equal, as it is cylindrical and therefore allows more saturation without overflowing, which is an issue with oklch.

What solution would you like?

Add okhsl and okhsv to the bevy_colors.

What alternative(s) have you considered?

1. Deal with less saturated colors
2. Use math on my side to calculate the highest chroma for a given hue

I could try implementing this for myself, but I'm new to the codebase and don't really know how to compute some values of the traits.

I'm okay with this. Please feel free to open up a draft PR with todos for the section you're not sure on; we can help mentor you during that.

Should I implement the clamping? It seems that the clamping is a major feature of the Okhs(l)(v) color spaces, but also takes around 200 lines just to do that.

Let's leave it out for now: we're generally not clamping our other color spaces and we can add that later.

I am also interested in this feature, the C++ header is quite easy to translate line by line.

I tried writing this, but at one point I just couldn’t get the rust code to work the same as cpp even when I tried translating it line by line. That was a while ago and if you feel like it, you can try it. Honestly I have partially given up.
