- Fixed KeyError preventing playlist downloads

- Fixed missing imports causing `NameError` on deemix patch

- Fixes 85, `self` missing from class method args

This release features a prototype of the library upgrade feature that was previously available in beta during Q4 2022. This will generate a text file containing track IDs or album IDs of every MP3 file in your library for you to pass into the `download` command. This release is mostly a maintenance release with those new features from the beta branch.

**New**:
- (library) Added new commands to upgrade library: `deemon library upgrade`
- Run `deemon library upgrade --help` for usage information
- (library) Added `--album-file` to download command to support new Library Upgrade feature
- Added option to also monitor artists from a playlist with `--include-artists`

**Changes**:
- (download) The `--file` option is deprecated in favor of `--artist-file` and `--track-file`

**Fixes**:
- Patches a bug in deemix 3.6.6 causing a TypeError when no UPC barcode is found on a release in the pathtemplates.generateTrackName method

This update includes a modified requirements.txt to include the latest setuptools package to mitigate CVE-2022-40897.
