WebP Support (#581)

* Added trackby so when series scan event comes through, cards can update too

* Added chapter boundary toasts on book reader

* Handle closing the reader when in a reading list

* Somehow the trackby save didn't happen

* Fixed an issue where after opening a chapter info modal, then trying to open another in specials tab it would fail due to a pass by reference issue with our factory.

* When a series update occurs, if we loose specials tab, but we were on it, reselect volumes/chapters tab

* Fixed an issue where older releases would show as available, even though they were already installed.

* Converted tabs within modals to use vertical orientation (except on mobile)

* Implemented webp support. Only Safari does not support this format natively. MacOS users can use an alternative browser.

* Refactored ScannerService and MetadataService to be fully async
