Album sorting using path, plus genre name encoding

Hello JF, please see there two changes in order or relevance

• Add support for path in sorting album tracks. So if navidrome recognizes one album even if there are two or more variants, we use the path to sort the tracks. I also try to recognize path element like "Disc1", "Disc 1", "CD1", "CD 1" etc. Report real path must be enabled in navidrome in order for this feature to work properly. If not enabled, things will still work but tracks will be mixed, so we would see multiple track 1, then multiple track 2, etc

• Encoding/Decoding of genre names so I avoid that strange characters are put on the objid
