Split database complete into media and attachment complete?

With the new possibility to load only certain attachments of a database, a database will not be marked as completely loaded in cache when all media files and tables are there, but attachments are missing. This has the downside that audb.load() will scan for missing media files when called again even though all media files are downloaded.

So maybe it would make sense to split up the information if all files are loaded for the different types of files.

The same argument holds for loading only a single table, which still contains all files.

I think the implementation overhead is too much, compared to the small gain we would get here.
