Changed CMakeLists.txt to set the C standard to C11. Added multiple binary image files for new visual assets. Added several new image files to enhance rendering capabilities. Changed stb_image.h to improve support for various image formats. Changed ray tracing engine to enhance ray creation and intersection. Changed triangle structure to use a vertex array for better attribute handling. Changed scene initialization to accommodate new texture management.
