Render to PDF and fix some issues

[nealrichardson]

This PR adds the style sheet and quarto config to render to PDF. Other changes:

• Set width = 64 globally for PDF, so table/tibble printing is narrower
• Disambiguates footnote anchors, which caused problems for PDF * Temporarily comments out datasets_pums.png, which xelatex choked on as too large somehow.

Running list of other things we need to fix in the PDF, not comprehensive but just stuff I noticed:

• [x] Many code examples overflow the width. https://github.com/arrowrbook/book/pull/12 solves many (all?) of them, we should probably just merge.
• [ ] There is a warning that our bibliography is empty and we don't have any citations. I think this could just be because we have bibliography: references.bib and related bibtex stuff in the _quarto.yml file. IDK if we need a bibliography or if our footnote references are ok (I haven't read the style guide). We do have several things in footnotes at least that would be candidates for a proper bibliography.
• [x] We have some weird footnotes within footnotes because of how the PDF is rendering [anchor](url). We either need to change how we do that globally, or find a way to leave that like that for the HTML version and make the PDF handle it differently. (fixed using conditional logic)
• [x] index.qmd says "this is the website for...", so that won't work. We need to conditionally hide that bit in the PDF.
• [x] Getting Started plots: title does not fit (should title and subtitle move to fig captions?), line labels overprint each other
• [x] CRS plots (section 8.3.1) have subtitles that overprint
• [ ] Yeah, I think all of the plots need figure numbers and titles and captions governed by quarto, they look off without them.
• [ ] Table 5.2: Comparison of formats supported by Arrow is empty: the ✓ aren't printing. (https://github.com/arrowrbook/book/issues/13 ?)
• [x] Page header has title and BIG SUBTITLE. This comes from the intersection of this bit from the Quarto LaTeX template and how the krantz.cls uses \maketitle on the page headers. It's not obvious to me how to work around that, but maybe it's not something we have to resolve, maybe the typesetters will just get that right.
• [ ] We're definitely short on page count :/

Final question: by default, quarto render renders all formats, so both html and pdf. You can pick one locally by doing quarto render --to pdf. But in CI: do we want to only render HTML? Or, render both, and maybe put the PDF in a build artifact? We probably don't want what I imagine is the default, which renders both and then deploys both--I don't think we want the pdf version of the book on the website. In this PR, I switched it to just do HTML and made https://github.com/arrowrbook/book/issues/17 for us to sort out enabling it.

CRS plots (section 8.3.1) have subtitles that overprint

I can handle this one

Another thing I noticed: at the end of the intro section for https://arrowrbook.com/datasets.html we have paths that are on my machine (and also quite long) could we post-process those to remove the personal path bits which would also make them shorter too?

Hmm, the datasets png still doesn't look right.

Made followup issues for the things I see left, merging this one.
