Binvox-like material parsing with material names

[Enchoseon]

Having the ability to control the blocks with material names (like Binvox's material parsing) would allow us to have a higher level of control over the final output before exporting to an obj.

(Example: Geometry with a material named "material_glass" would be turned into "minecraft:glass", "material_white_stained_glass" into "minecraft:white_stained_glass", etc.)
