[BUG] Missing track number in metadata

[rattrayalex]

Describe the bug
When I download an album with this tool, it does not include the track number in the metadata (or in the filename) so the tracks play out of order.

To Reproduce
I downloaded this url: https://open.spotify.com/album/1vz94WpXDVYIEGja8cjFNa
and opened it in the macos system inspector and VLC.

Additional context
I moved to https://github.com/spotDL/spotify-downloader instead, which allows formatting the name with {track-number} - {title} and seems to have many other nice features
