Refactoring ottrpal package

[cansavvy]

The ottrpal package has been left to decay and even started out as a bit of a hodgepodge.

I'd love to take a whack at reorganizing, restructuring and cleaning.

This would include tackling long standing issues like:

• Unit testing! ottrpal doesn't have unit testing! Unit TESTING! #130
• Renaming functions so that they are clear that they work with quarto too!
• Functionalizing the scripts that exist in ottr-reports Get rid of the scripts/ folder OTTR_Template#572
• Cleaning up ottr-reports documentation
• Address the deprecation of clean_envir in bookdown #71

I think this is the order of operations for this:

1. Determine essential functions for ottr
2. Design and implement test-that tests for these functions
3. Once tests are in place start the refactoring piece by piece (the unit tests will ensure or identify when we make breaking changes)
4. Continue to refactor using this cycle of development
5. Then create a release and send updates to CRAN and rebuild the docker image.

Should also pull the most useful parts of cow package and incorporate them

I think mostly borrow_chapters get_pages_url are what we need
