Add texture maps in Material panel for ambient occlusion, subsurface, height/displacement

The textures in the Material panel are extremely useful when we have models with UVs, but I miss some of the most common maps that come with PBR materials. Most of the times, the ambient occlusion map is always present and we can’t use it right now, as well as the subsurface and the height/displacement maps.

I’m not talking about baking to export, but using already existing (downloaded) images to be imported in the Material panel and used within Nomad.

Thanks for your amazing work!
