CLN: Format comments in frame.py to comply with PEP8 line width
Hello! While becoming acquainted with the code, I noticed that the frame.py file had a lot of comments with a length over PEP8's 79 character limit.

I reformatted all comments to the 79 character limit, unless they involve command-line related code examples.

Let me know if there is anything I can do to help.

Thank you!
Thanks for working on the proposed changes @TheCheerfulCoder. We validate in our CI that all rules from PEP-8 we care about are enforced. You can check the code checks jobs to get an idea all the things we validate.

We're happy with these longer lines, and merging this PR means we lose the value that `git blame` provides for a significant part of the code. So I'll be closing this PR, as I don't think we want to merge this.
