Hi,
would it be possible please to add support for directory listing?

My usecase is indexing of local folder without external repository.
It means Zoekt links search results to internal file viewer at '/print' route.
It would improve useability a lot, if user would be able to navigate from file to parent folder and from folder to other files in it.
Also links in search results may point directly to directories on file paths.

I tried to adapt the '/print' route template. But it seems it will require more changes in source code.

Thank you for great app!
