Error when accessing PhysicsDirectSpaceState
Calling `directSpaceState` on `World` causes
`ERROR: : Nim constructor not found for class BulletPhysicsDirectSpaceState
   At: godotnim.nim:280`
and returns `nil`.

Here is a simple project which reproduces this behavior when the window is clicked: https://github.com/alexpardes/godot-nim-stub
I am using Windows 10, Godot 3.2.3, and Nim 1.4.2
