Lotta reworking to make this work
Seriously a lot of reworking to make this work
* Cleanup + Some documentation
Because I won't "know my own code"
I genuinely do not know what I just coded
* Swapped around icons for double page in chapter sheet bar
Since it was confusing even me
* Fix shifting not updating the ui, nor shifting back to the right page
* Fix changing chapters
* Fixed Prev Chapter transition page jumping back 1
* Fixed progress spinner for single page loading
* Fix the case of a second page shifting for full width while double shift is on
It would unshift the pages in this case, requiring another shift back
If this sounds confusing or complex, it's because it is

(more spoilers it still will break again)
* Fix Retry in double mode
* Set gifs as fullpages
* Fix going from automatic to single/double page layout
* More cleanup, more comments
* Fix changing page layout when on a transition page for a manga with a single chapter
The edge cases you can find....man
* Restore shifted pages on activity recrreation
* Adding a "beta" tag to page layout
IMO it's absolutely solid and release candidate ready, but you can get away with so much by calling something a "beta" or an "alpha"
also bumping up to kotlin 1.4.20 and using jsetbrains kotlin for parcelize (needed for mass migration)
With this we can close#684 because we are TRULY finished
