Custom physics engine

Working on creating the smallest, most lightweight physics based 3D engine ever. Well me and Argon are. Had issues with adding more than 2000 physics bodies. But after some tweaking, we are now able to add roughly 20.000 physics bodies at once, while having around 2000 simultaneous collisions. All while still weighing in around 90kb impulse is built entirely in rust. and ofcourse using dialkit from @joshpuckett
