Feature request: semantic token highlighting

[apetresc]

A big feature request :) The latest Neovim 0.9.0 release added support for semantic token highlighting. It would be amazing to see them in Zenburn, although I understand that probably requires us taking a bit of artistic license since the OG zenburn simply wasn't designed with this in mind.

Would you be willing to accept a PR for this?

I would most definitely accept a PR for this, this is Zenburn for the modern age after all. Only caveat is I want to avoid adding more colours if at all possible so I would prefer using the palette that is already available plus modifiers like bold etc.

I was wondering what this means. I found this help page here, maybe it can be useful https://gist.github.com/swarn/fb37d9eefe1bc616c2a7e476c0bc0316
