Convert perspective square to perspective cube
- Finds perspective vanishing points
- Uses law of ratios to find correct volume
- Returns 2d-Points of the cube bounds
- Carthage

- Add support for 1 point perspective Quadrilaterals ✅
- Add support for horizontal 1p quads (co-linear, epsilon etc) ✅
- Add support for square w/o perspective ✅
- Optimize the math for performance 👈
- Account for object relation to POV 👈
