Implement "file browsing" way to listen tracks without metadata
Steps to reproduce
Go to /library/me.
What happens?
I installed funkwhale with docker and imported all my music files. I have in the filesystem 5964 files. Funkwale library says there are 5586 tracks. (The difference can be explain by non audio file / import error due to some caracters/...)
However, I notice, I cannot find 1743 "tracks". These tracks are mainly extracted from videos (podcast). So they don't have any metadata.
What is expected?
Be able to see all tracks. Maybe with as title the filename, the artist name "unknown" and album name "unknown".
Context
Funkwhale version(s) affected: 1.1.4
