Alphabetize authors by last name.

Note: leaving myself for now as first author til I can confirm Sylvain is OK
ending up first, as his last name would put him first on the list. I don't want
to do that in case he prefers not to appear listed first. Otherwise the
previous order was more or less random as it came from typing in names from a
Zoom call as I saw them on the window.
