Support oklch in the color picker

This is an alternative color space to the typical RGB, and it would be awesome if the tweakpane color panel supported oklch as a raw color input within the selector. <3

I agree, but I think it would be very tricky for the core Tweakpane project to support the full breadth of the CSS color spec without breaking the "dependency-free" design philosophy.

As an alternative, I just released a Tweakpane plugin that adds support for oklch and any CSS 4 color format (it uses Color.js under the hood), plus some other conveniences like support for tuples:

For now, the plugin reuses the built-in Tweakpane color widget UI, so you can't actually pick wide-gamut colors that are possible to represent in oklch, but I hope it's a start!

Support of HTML Color Names also would be useful. Especially, for the regular end-users.
