Support hsluv color constructor about ratatui HOT 5 OPEN

I like this idea. But I'd prefer to avoid using palette (or any other deps) just for that.

I'd suggest putting this behind a palette feature. I believe most people will still use rgb.

If not to hard, we could also implement it by hand, but didn't really find a clear formula so maybe that's too much.

My understanding is that it is a series of transformations to go from hsluv to rgb, and I'm assuming we wouldn't want to maintain that.

Definitely needs a feature flag. I recall seeing a create that does more generic conversions like this. I'll find a link later today.

I also think that this is a nice feature and we can gate it behind a feature flag for avoiding additional dependencies as default.

https://github.com/Canop/coolor was the crate I was thinking of. It's not quite what we're thinking of here though.
I mentioned perhaps doing a Ratatui feature for it in Canop/coolor#2, but never got back to that.

Are there any other crates that already do the conversions between libraries?
