Support all color values from CSS Colors Level 4 spec

[htunnicliff]

@adamwathan in response to your ask that I include support for space-separated RGB values in addition to space-separated HSL values for #5003, I did some research.

I discovered several newer (well-maintained) color libraries that have full support for all color types used in the CSS Colors Level 4 spec.

As a result, I replaced the color library with culori instead. This supports both RGB and HSL colors with and without space-separated values, as well as all of these color spaces.

P.S.: Culori's API is quite robust, and as a result could support lots of cool future Tailwind color modification features, if desired 😄

Resolves #4677.

Hi @RobinMalfait and @bradlc 👋 – would you be able to take a look at this PR that improves Tailwind's support for newer CSS color formats?

I was chatting with @adamwathan about it in #5003 but it looks like he is not available at the present time.

Hey Tailwind team; following up here. It's been about two weeks since I submitted this PR. Is there something else I should do in order to receive a review?

@htunnicliff it's the holidays 😜

Hey! Thank you for your PR!
Much appreciated! 🙏

I fixed the conflicts and merged it manually. Not sure why GitHub didn't mark this as merged, but your commits are there!

Hi everyone. Happy to see this PR merged! The latest package version is [email protected] and includes things like parsing the color()syntax, which may be useful.
