Support for Java Key frame Animations

The Java Key frames were used in 1.19 to create the Frog's and the Warden's animations. Now, if this feature was added to Mcreator, it would help players reduce the amount of plugins they have to use and make everything neater. 

For instance, players would no longer have to use GeckoLib to animate entities. (Who knows, maybe users wouldn't even have to use player animator? I'm not sure how that would work though.) More importantly, according to Kleiders, this would add the ability to animate Java models that are rendered over the player, and entities, using his plugin, Kleiders Custom Renderer. 

I would REALLY appreciate this feature, thanks for your consideration!
