Set C standard to C11 and add new assets

Browse Source 
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.
