Additional Material Import Datasets and Material Enum Additions

[kayleighhoude]

Description:

Addition of Material Import Datasets (based on research by @jschmidt00) for:
-Aluminium
-Asphalt
-ClayBricks
-Carpet*
-Cobalt*
-FloorCover*
-Glass
-Gypsum (re-add with appropriate material enum entry)
-PVC*
-Timber
-Zinc

*These materials are not currently in the materials enum and need to be added

Concrete should be removed from the enum, as it is not a raw material

@jschmidt00 based on the composite materials research you are doing, let's decide if we need the following in the enum (and what additional datasets/entries we need!):
-Brass
-Ceramic
-Iron
-Lithium
-Plastics
-Rubber
-Silicon

@kayleighhoude based on our email exchange this morning, I propose we need the following:

• Iron ("metallic iron, from which steel is derived, must be extracted from iron ore")
• Fly ash
• Limestone
• Coal
• Polyurethane
• Glue (added since our email)
• Maybe scrap steel
