Add support for UnoCSS

[MrFoxPro]

UnoCSS: https://github.com/unocss/unocss
It should be similiar to tailwindcss plugin.
Example plugin for nvim

See #2551 (comment)

Here it looks like the config would be something like

{
    "clients": {
        "UnoCSS": {
            "enabled": true,
            "command": ["unocss-language-server", "--stdio"],
            "selector": "source.css"
        },
    }
}

A separate package similar to LSP-tailwindcss could be created to automatically install & update the server. This would also allow to handle custom requests if that is applicable to this server (probably not necessary). We could create a new LSP-UnoCSS repository under the sublimelsp organization if desired, but someone would need to maintain it.

Wow, that works, thanks! I looked into docs and I didn't realize that its called "Clients", I searched for "Custom server" or something like that.
