Feature Request - Rock Processing

[voicey99]

Now Rock production is coming to MKS, this will completely throw off the balance for the ART Mass Driver. This means that, given the very high production rates, a mass-driven vessel could touch down on a planet with a tiny drill, refuel and be off again in minutes. As such, a way of countering this would be to change the Mass Driver to run on Rock Dust rather than raw Rock. The Jaw would produce Dust instead of Rock, the extraction modules could run on both raw and crushed rock (with a switchable bay system like that of MKS, but would cost nothing to switch) and a new ISRU model would be added to process the raw MKS-provided Rock into Dust. Provided with a crusher model and texture, I would be able to do the rest.
