Folder support for OPDS

[Fmstrat]

Describe your suggested feature

Supported extensions like Kavita offer folders in OPDS. When visiting the primary OPDS URL for example, there are sections like Reading Lists that allow you to filter down collections for reading order, Recently Added, All Libraries, etc, however Mihon goes straight to showing all files in all libraries at once. It would be nice to be able to navigate this hierarchy.
