* BUGFIX
* Wrap audiofile.tag.save specifically in another try catch to catch an error saving.
v2.2 ID3 tags, which the library apparently doesn't support.
* I will continue catching cases like this one by one as they come up,
rather than use a catch-all,
because I would like to preserve, somewhat, the cases I need to eventually fix.
* No ETA on fixes, I don't have enough time to get to everything I'd like to work on.

* BUGFIX
* Wrap process_tags with a try-except to catch something wrong with the tag setting.
* Needs more thorough look but don't feel like it right now.

* DEV
* Replace Stagger library with eyeD3. eyeD3 is more actively maintained.

* BUGFIXES
* Update dependencies and verify functionality.

* BUGFIXES
* Fix a typo in text output spacing.

* BUGFIXES
* Be more conservative about ID3 tag editing. Tested with a podcast recently that is .m4a
files, and they broke on download because those files can't have ID3 tags.
