Fix/journal styling

[kamicut]

Checklist from @bwbaker1's feedback. doc for more details and screenshots.

• Centered title
• Unique affiliations should be listed with superscripts
• Duplicate affiliations should not be listed
• Corresponding author name/email should be listed right below the affiliations and above the keypoints.
• Key Points should be bulleted (previously, a carriage return automatically adds a bullet point)
• Remove document information (Version, Release date, and DOI)
• Page break after Key Points
• Keywords have double colons (::). One of these needs to be removed.
• Algorithm Usage Constraints should be section 4, not section 9
• Fix remaining heading numbering (see doc, point 9)

This is what the affiliations look like now in the draft PR:

Bullet point styles for key points

Everything you checked off looks good @kamicut!

One issue I found is with multi-level lists – they only have the content, and not the list itself. Do you have any idea why that is?

☝️ somewhat works locally and on staging for document pdfs but not for journal PDFs. For document pdfs, the levels are labeled, but not correctly.

If these are easy fixes @kamicut, let's add them to this PR, otherwise we can merge it as is and ticket the bugs.

I've pushed a fix for that issue in this PR @wrynearson
