support unoCss

[oSethoum]

Hi, please add support for adding unoCss here's the docs https://unocss.dev/integrations/svelte-scoped

[bato3]

They have couple integration methods for SK/Svelte https://unocss.dev/integrations/svelte-scoped#when-to-use

Use Case		Description	Package to Use
Smaller apps	❌	Having 1 global CSS file is more convenient. Use the regular Vite plugin for Svelte/SvelteKit.	unocss/vite
Larger apps	✅	Svelte Scoped can help you avoid an ever-growing global CSS file.	@unocss/svelte-scoped/vite
Component library	✅	Generated styles are placed directly in built components without the need to use UnoCSS in a consuming app's build pipeline.	@unocss/svelte-scoped/preprocess

I think we should omit the last option for component libraries, svelte-add is designed for apps. As of now I would personally choose the first option, because it's the closest to all other styling adders that we have (bulma, bootstrap, etc.)

But maybe that may change later.
