- **Bug Fix**: Fixed `KeyError: 'tracknumber'` when downloading playlists.
- **Problem**: The default `playlist_name_format="{tracknumber} - {user[username]} - {title}"` caused a `KeyError` because `tracknumber` was not properly passed to `scdl`'s file naming logic.
- **Solution**: Updated the default `playlist_name_format` to `"{user[username]} - {title}"`, removing the dependency on `tracknumber` to ensure compatibility with `scdl`.
- **Improvement**: Added detailed error logging for timeouts and subprocess errors, improving debugging capabilities.
- **Distribution**: Published the library on PyPI, making it available for installation via `pip install soundcloud_downloader==0.1.4`.
