Add hypothes.is to the Book Of Ohdsi website so anyone can annotate and comment on the book

[ablack3]

Hypothes.is can add interactivity to a book created with Rmarkdown. Readers would be able to ask questions, suggest edits, and make comments all in their web browser.

Here are examples of Rmarkdown books that uses hypothesis.is:

• https://www.crumplab.com/ResearchMethods/
• https://jrnold.github.io/r4ds-exercise-solutions/

Here is some documentation about how to add this to a book: https://www.crumplab.com/OER_bookdown/hypothes-is-1.html

This functionality might make it easier for more people in the community who are not familiar with Github and Rmarkdown to comment and suggest edits or highlight places for clarification.
