Comment and URL Tags with Mutagen (Part 2)

In Comment and URL Tags with Mutagen, I presented the code that I use to add support for comment and URL tags to the EasyID3 class. I am not sure if such changes are desired upstream, but I went ahead and created a GitHub issue referencing my proposed changes.

Note that I also updated my code. I stopped using “f-strings” because I bet that Mutagen supports older versions of Python that do not have them. I also cleaned up the code to make it clear that a “frame ID” includes encoded parameters. I updated the code and wording of my blog entry to reflect this.
