Still got a bug when colliding with edges at some specific rotations. Probably fucked relative position conversion somewhere and using a local pos instead

Super stable collision resolution
...
- Store collision manifold points as local to body before applying them, this way penetration can be calculated exactly for each contact point
- Fix implementation error in closest_point_between_segments
- Calculate separation for each contact point separately

Proper stable collisions

Turns out when you get a collision pair YOU SHOULD HANDLE CONTACT RESPONSE FOR BOTH BODIES, NOT JUST ONE OF THEM
Otherwise they move and their next collision (if a->b, b->a are found and resolved separately) they might penetrate badly or worse and everything blows up
This is probably not as important in sequential impulse type solvers because the actual position update is deferred, but in a position based one it's pretty important as it turns out.
It's also better for performance because I don't have to run the collision query for the same two bodies two times
