Assets are duplicated on multilingual sites

[illfygli]

When using zine.multilingualWebsite, it seems that assets are duplicated for each Site/output prefix.

This is reproduced on ziglang.org:

https://ziglang.org/it-IT/ziggy.svg

That means that assets are loaded anew when switching languages, so it's a performance issue as well.

Thank you for Zine, it is great ♥

Zine should allow de-duplicating assets in multilingual sites, but currently does not. Actually implementing this enhancement requires thinking through the new output directory semantics and how to expose these knobs to the user.

I'm prioritizing other features at the moment but I will get back to this eventually.
