Updated Magisk fragment to Kotlin

Exported old update card to special xml include where binding takes care of everything that had to be done in code beforehand.
Added several easing functions and enums.
Backported some classes and functions from the old fork

Expect major breakage. Literally nothing works as the functionality needs to be implemented
