[PDF] Create a demo of VitalSource on PDF

We'll be done when:

The developer of the feature can complete the scenario laid out below
A "laundry list" of next steps exists to capture the remaining tasks required to get PDF ready for launch.

Scenario / story

I'm the person who wrote the code. We're in a meeting giving VS the update that we're ready to roll this out in a limited pilot for the Spring. We've already learned from profs that having H will prompt them to force students to opt-in/buy the textbook via VS, so we're adding real value to their business.

To prove we can cover the entirety of their catalog (both EPUB and PDF) and motivate them to begin recruiting their own customers for use, we show them the work we've done to solve for their PDF reader:

Assuming that:

I'm in Canvas
I've logged into VS ahead of time to avoid any login interstitial
I've picked a PDF book from VS I know I have access to
- :information_source: For the demo, we can pick the best book, but eventually this will need to work with any of a representative sample
- [ ] Get a representative sample from VS and include it here
I've created a new Canvas assignment and select Hypothesis
I do not make this a group assignment
I opt to launch the app in a new tab

I can do the following demo:

:bust_in_silhouette: I start as a teacher
I launch the Hypothesis tool to set up the assignment
I select the VitalSource source option
I drop in a full VS bookshelf link
The book loads with a thumbnail of the cover
I select a chapter from the chapter menu to assign that chapter as the entry point
- :information_source: It does not need to keep users from going past the assigned chapter for the demo
:bust_in_silhouette: I switch to a student
I launch the assignment, which kicks me into a new tab. The sidebar shows up on the right side of the viewer.
When I highlight some text in the PDF and get the annotation pop-up
When I hit Annotate, a draft annotation appears in the sidebar. I can save it like normal.
- :information_source: I've intentionally not mentioned page notes or highlights, in case it cuts scope :shrug:
When I drag or scroll the VS pager and the pages change but I stay in the same chapter, my annotations in the sidebar stay there
- :information_source: It's not an issue for the demo, but we should keep in mind that in the future, we may need to bucket posts by assignment, not chapter, and keep them from going past the assigned page range.
When I switch to the next chapter using the table of contents or prior/next buttons, my annotations in the sidebar switch to display the annotations associated with the new chapter_

:heavy_plus_sign: For the future

Adding an ISBN should also work (should already be true)
The same flow works for highlights
Page notes also work
When I open Notebook. My new annotations show up next to my other posts from other assignments outside VitalSource, linking to the VitalSource book correctly
