Review and improve the effect measure modification chapter

Overview

In the Fall of 2023, I moved over a bunch of stuff from PowerPoint slides (nearly) verbatim. I was in a rush, so I told myself to move it just move it over and improve it later.

Go back, reread, and improve. PowerPoint doesn't always translate perfectly to book format.
