Add option to use filenames as titles instead of metadata

[pragma-]

Very often I'll download a season of a show that has filenames like Show.Title.S01E01, Show.Title.S01.E02, but the title metadata for every file only has "Show Title" without any season/episode information. This makes it extremely difficult to watch the shows in the correct order because Jellyfin sorts these randomly. If we could opt to list the shows by filename instead, everything would be perfect. This is a heavily requested feature that every other media library already supports. Please add this to Jellyfin.
