#380, #375

Expected

The CFI blacklist to have one single source of truth

Observed

The CFI blacklist is duplicated in the ReflowableView and OnePageView

• readium-js/readium-shared-js/js/views/one_page_view.js:935
• readium-js/readium-shared-js/js/views/reflowable_view.js:63

Additional Information

The issues referenced here were caused because one of the cfi blacklist set went out of sync from the other.
