Local files aren't moved with website building.

An issue I was running into while trying to get the snapshots working in #6 , was that when trialling it on a quarto blog, while the molstar.molj file was in the correct location with the original index.qmd document, upon actual rendering of the website with quarto render or quarto preview everything was copied to the docs folder, but the molstar.molj was left behind and thus broke the URL.

Is there a way to mark specific files inside of the Lua / Pandoc to be treated as assets by Quarto? I assume that would fix the problem. Similar to what is done with images and other assets already inside of Quarto.
