[Bug] Grinding nuggets gives two dust (MCL)

[ThePython10110]

In MineClone2 (and therefore probably Mineclonia), you can grind a gold or iron nugget to get two dust. Since a nugget is 1/9 of an ingot, it should take at least 9 nuggets to make 1 dust.

[Buckaroo Banzai]

The original idea (from the default game) was to provide a better way to process lumps to ingots with two times the yield.

• "normal" smelting process: 1 lump -> 1 ingot
• grinding process: 1 lump -> 2 dust -> 2 ingots

Since a nugget is 1/9 of an ingot, it should take at least 9 nuggets to make 1 dust.

Sounds good, but i don't think the input material-count can be specified in the recipes 🤔

Relevant code sections

Grinder recipes:

technic/technic/machines/register/grinder_recipes.lua

Lines 16 to 22 in da0378a

 -- Dusts 
 {mat.coal_lump,          "technic:coal_dust 2"}, 
 {mat.copper_lump,        "technic:copper_dust 2"}, 
 {mat.desert_stone,       mat.desert_sand}, 
 {mat.gold_lump,          "technic:gold_dust 2"}, 
 {mat.iron_lump,          "technic:wrought_iron_dust 2"}, 
 {mat.tin_lump,           "technic:tin_dust 2"}, 

(mcl recipes might have to add a recipe-switch here ^ directly instead of using the material 1:1)

Game/Material switch:

technic/technic/materials.lua

Lines 11 to 14 in da0378a

 gold_ingot = has_mcl and "mcl_core:gold_ingot" or "default:gold_ingot", 
 gold_lump = has_mcl and "mcl_core:gold_nugget" or "default:gold_lump", 
 steel_ingot = has_mcl and "mcl_core:iron_ingot" or "default:steel_ingot", 
 iron_lump = has_mcl and "mcl_core:iron_nugget" or "default:iron_lump",

Everything for base machines should be able to handle item count in input, alloy recipes have examples for this.

So just making it 9 in 1 out should work.

imo the proper fix is to have the grinder be able to grind ore blocks and raw ores since those are analogous to ore lumps in minetest game, and not being able to grind nuggets at all.

@nonfreegithub what do you think, since you wrote the mineclone compatibility PR?
