This commit refactors the Camera class to add clarity and better logic: - Integrates variables directly from constructor to the header for cleaner code - Adds getters and setters for fov, speed, cameraSensitivity and position - Duplicates projection matrix from cube to camera - Adds comments to the header file - TODO: the projection matrix from the cube loop function must now be replaced by the call to the `glm::mat4 getProjectionMatrix()` camera function
