Add an exam checklist document

[willGraham01]

Adds the exam-checklist folder, which is ignored in the notes build so shouldn't hurt the JupyterLite stuff that's going on.

Other than that, the document is essentially a 3-page summary of the things that have been studied in the course (and/or assignment!) that students can expect to be "fair game" for a question in the exam. The document is not meant to be a revision sheet, so the majority of topics are simply listed but not explained - the students will need to look at the course notes / assignment / exercises to figure out what they should know in detail.

The document is compiled by building course-knowledge-checklist.tex with your favourite $\LaTeX$ compiler. The images used in the document need to be present on the system (hence the rather awkward addition of some .jpgs - sorry 😢 ). scaling-laws.py is a script that generates the corresponding images/power-law-scaling.svg image, included in case we need to adapt the example in future / want to expand on it.

(Sorry for scary diff, but ~4100 lines of that is just the 2 SVGs, so don't worry about it...)

Amazing job!
Just some small typos. And then the question of how we give credit to those images?
Also, should the CI build the pdf from this?

I think this caption needs more explanation. I don't really understand the image itself.

I've swapped it out now for a new plot similar to the power law scaling one, since if one is explained then the other should be too.

We could make it do that, but TBH I don't think it's worth the effort of doing so. I don't envision this is a document that will change much at all, unless the course notes drastically change too. And it's not too hard to just git clone and then latexmk the file.
