glTF scene compatability

glTF scenes require vetex UVs, normals and tangets along with materials for all meshes.

The glTF sample assets can be used to test the path tracer but some might need to have tangents added to them.

Command line arguments

• --scene-path sets the path to the glTF scene to be rendered, no default this argument is required.
• --num-samples sets the number of samples which are taken every frame, default is 1.
• --num-bounces sets the number of bounces a ray can make before being terminated, default is 2.
