Soft bodies physics simulation

All memory leaks fixed

Bullet vs PhysX -> Bullet since only PhysX5 has soft bodies but needs Omniverse app (still I miss Nvidia GPU)

OpenGL vs Vulkan vs Direct3D vs Metal -> OpenGL

Still needs refactoring but exam date near

Soft bodies work correctly and can be generated from any kind of imported model

FPS stable between 55 and 60

Optimization of soft body simulation paramaters in Bullet

Keep solver iterations low otherwise FPS drops

Refactor also both vertex and fragment shader

Keep GitHub repo public until exam date

Quality is low because I had to compress it quite a lot
