Lunar Surface Drill really needs a re-balance.

Right now, 90s for 20% chance at a tungstate/scheelite dust means ~52m30s for 2 tungsten dust at the cost of ~4 titanium drill heads. These can stay painful to automate, but the yields should be roughly:

• stainless steel drill head yields ~16 W on average
• titanium 32 W on average
• tungsten carbide 64 W on average

We can make all yields better and play with power requirements or durations to encourage better drill tips.

• stainless yields 7 ore each at 50%, with 0.06 use rate (~16 runs/ head), 75s (0.8 W per 60s)
• titanium yields 7 ore each at 75% with 0.045 use rate (~22 runs/ head), 60s (~1.5W per 60s)
• tungsten carbide yields 7 ore each at 100% with 0.03 use rate (~33 runs/head), 30s, (4W / 60s)
