[Suggestion] Variable return of exotics by drill level

Have the different drills return a different percentage of exotics per vein. For example, if a vein's base amount is say 180 to 220 exotics, the biofuel drill would return maybe an even amount, the electric would return 15% more, and the workshop drill would give maybe a 25% increase over the base amount. in other words, if your randomize count for a vein was 220, it would give 220 for biofuel, 253 for electric, and 275 for workshop drill. In other words, make mining veins with improved drills somewhat similar to how pickaxes improve mining nodes of exotics. Make using the better drills more profitable for the time and effort.
