Subject: feat Make camera and model instance more abstract

* src/camera.cpp src/camera.hpp: Remove the camera as Vector3D and
Rotation3D are going to replace it.
* src/model.cpp: Add draw command as instances do not exist anymore.
* src/model/instance.cpp src/model/instance.hpp: Remove the instance as
Vector3D and Rotation3D are going to replace it.
