Feature request: OKLAB support

[sergio-ezquerro-ochagavia]

As stated in the title, I request support for oklab colors.
This change could make it (much) easier to select color palletes in the future

I'd like to second this motion. Love the oklab colour space and use oklch for all my colour schemes.
Right now the extension Color Highlight supports (some) oklab syntax, but doesn't support css variables (one of colorize's many lifesaving features). So I use it to view what colours I'm assigning my variables to but can't see what they are when I use them.
