Complete TODO of replacing quatToXyzAngles with toEulerAngles

[FluffyOMC]

Replaces angleBuf = quatToXyzAngles(rot.unit(), angleBuf); with EulerAngles eulerIntrinsic = rot.unit().toEulerAngles(EulerOrder.XYZ);

Since this also makes quatToXyzAngles now unused anywhere in the code, I decided to delete the unused function to save space.

Looks good, I wanna do a quick test with it to make sure functionality is the same, but this todo has been here for a bit, good job

Mhmm! Just doing what I can, not the best at Java I took like, a single class on it.

And I don't know much about the functions methods in this project.

Rust is more my thing but uh, I don't see much in the rust repo that is beginner lol

we also have some rust in here if you want to refactor, its in gui/src-tauri

EulerOrder must be ZXY
