Wrong texture lookup - PbrMetallicRoughness class uses index of texture to lookup image

Hey,

In the attached example it seems like the code in Material.py is using the index here:
Material[6]['pbrMetallicRoughness']['baseColorTexture']['index']

To find the image which leads to an error since the index should be used to find the texture object in 'textures'.

@jclarkk good catch, I'll work on a fix for this

@jclarkk just merged a fix for this: #143

Great, thanks!
