Adds support for multiple chapters. The previous version ignored any leading chapter numbers in the uri of {chapterId}/images/{image}. It now accounts for that and is working in a locally run user interface for an epub that was broken. I didn't check in the unit test over the GetBookPage method since it requires a specific file. I'll provide that in the PR description, though.
