OPDS Support (#526)

* Added some basic OPDS implementation

* Fixed an issue with feed href

* More changes

* Added library routes and moved user code to a method so we can hack in fixed code without authentication

* Images now load on the OPDS reusing our existing Image infrastructure.

* Added the ability to download and moved some download code to a dedicated service

* Download is working, pagination is implemented.

* Refactored libraries to use pagination

* Laid foundation for OpenSearch implementation

* Fixed up some serialization issues and some old code that wasn't referencing helper methods

* Ensure chapters are sorted when we send them over OPDS

* OpenSearch implemented

* Removed any support for OPDS-PS due to lack of apps supporting it.

* Don't distribute development.json nor stats directory on build.

* Implemented In Progress feed as well.

* Ability to enable OPDS for server. OPDS now accepts initial call as POST in case app uses username/password.

* UI now properly renders state for OPDS enablement. Added Collections routes.

* Fixed pagination startIndex on OPDS feeds when there is less than 1 page.

* Chunky Reader now works. It only accepts UTF-8 encodings

* More Chunky fixes

* More chunky changes, such a fussy client.

* Implemented the ability to have a custom api key assigned to a user and use that api key as your authentication token against OPDS routing.

* Implemented the ability to reset your API Key

* Fixed favicon not being sent back correctly

* Fixed an issue where images wouldn't send on OPDS feed.

* Implemented Page streaming and fixed a pagination bug

* Hooked in the ability to save progress in Kavita when Page Streaming
