Drawers, Estimated Reading Time, Korean Parsing Support (#1297)

* Started building out idea around detail drawer. Need code from word count to continue

* Fixed the logic for caluclating time to read on comics

* Adding styles

* more styling fixes

* Cleaned up the styles a bit more so it's at least functional. Not sure on the feature, might abandon.

* Pulled Robbie's changes in and partially migrated them to the drawer.

* Add offset overrides for offcanvas so it takes our header into account

* Implemented a basic time left to finish the series (or at least what's in Kavita). Rough around the edges.

* Cleaned up the drawer code.

* Added Quick Catch ups to recommended page. Updated the timeout for scan tasks to ensure we don't run 2 at the same time.

* Quick catchups implemented

* Added preliminary support for Korean filename parsing. Reduced an array alloc that is called many thousands of times per scan.

* Fixing drawer overflow

* Fixed a calculation bug with average reading time.

* Small spacing changes to drawer

* Don't show estimated reading time if the user hasn't read anything

* Bump eventsource from 1.1.1 to 2.0.2 in /UI/Web
