Continuous Reading for Webtoons & I Just Couldn't Stop Coding (#574)

* Fixed an issue from perf tuning where I forgot to send Pages to frontend, breaking reader.

* Built out continuous reading for webtoon reader. Still has some issues with triggering.

* Refactored GetUserByUsernameAsync to have a new flavor and allow the caller to pass in bitwise flags for what to include. This has a get by username or id variant. Code is much cleaner and snappier as we avoid many extra joins when not needed.

* Cleanup old code from UserRepository.cs

* Refactored OPDS to use faster API lookups for User

* Refactored more code to be cleaner and faster.

* Refactored GetNext/Prev ChapterIds to ReaderService.

* Refactored Repository methods to their correct entity repos.

* Refactored DTOs and overall cleanup of the code.

* Added ability to press 'b' to bookmark a page

* On hitting last page, save progress forcing last page to be read. Adjusted logic for the top and bottom spacers for triggering next/prev chapter load

* When at top or moving between chapters, scrolling down then up will now trigger page load. Show a toastr to inform the user of a change in chapter (it can be really fast to switch)

* Cleaned up scroll code

* Fixed an issue where loading a chapter with last page bookmarked, we'd load lastpage - 1

* Fixed last page of webtoon reader not being resumed on loading said chapter due to a difference in how max page is handled between infinite scroller and manga reader.

* Removed some comments

* Book reader shouldn't look at left/right tap to paginate elems for position bookmarking. Missed a few areas for saving while in incognito mode

* Added a benchmark to test out a sort code

* Updated the read status on reading list to use same style as other places

* Refactored GetNextChapterId to bring the average response time from 1.2 seconds to 400ms.

* Added a filter to add to list when there are more than 5 reading lists

* Added download reading list (will be removed, just saving for later). Fixes around styling on reading lists

* Removed ability to download reading lists

* Tweaked the logic for infinite scroller to be much smoother loading next/prev chapter. Added a bug marker for a concurrency bug.

* Updated the top spacer so that when you hit the top, you stay at the page height and can now just scroll up.

* Got the logic for scrolling up. Now just need the CSS then cont infinite scroller will be working

* More polishing on infinite scroller

* Removed IsSpecial on volumeDto, which is not used anywhere.

* Cont Reading inf scroller edition is done.

* Code smells and fixed package.json explore script
