Add depth sensing sample and OpenGL tests

- Implemented a new sample application in main.cpp to capture and display a live 3D point cloud using the ZED SDK and OpenGL.
- Created test_opengl.cpp to demonstrate basic OpenGL rendering with depth testing using two triangles.
- Added test_points.cpp to visualize a grid of colored points in OpenGL, showcasing point rendering capabilities.
