* add generic types to`Pokemon.getAbilityAttrs()`
* add invert check to `ProtectStatAbAttr.apply...`
This makes sure that a stat is only protected if no other ability inverts the change. E.g. `Contrary` inverts any decrease to an increase
* migrate contrary.test.ts to game.classicMode
* move `StatStageChangeMultiplierAbAttr` resolve above `ProtectStatAbAttr`
The effect of StatStageChangeMultiplierAbAttr is now applied before resolving any ProtectStatAbAttr. Thus the stage (level) of the BattleStat change was properly altered at the time of resolving the protection
* revert ability.ts changes
* add automated tests for `Clear Body` + `Contrary`
* StateStageChangePhase replace ~~`IntegerHolder`~~ with `NumberHolder`
Update Utils import and replace all occurcences of `Utils.`
* contrary.test.ts: remove `js` import
