get recipes from recipes json asset

[rom1504]

Yes mojang now store the recipes as json. Finally.

So we can just take that and convert it to our format (for 1.12 at least)

their format https://gist.github.com/rom1504/006a8109d74611b1a25d67272d6b4f20 is definitely more explicit and clear than our format https://github.com/PrismarineJS/minecraft-data/blob/master/data/pc/1.12/recipes.json#L5360 might need some more preprocessing for usage though (compared to ours)

How does their format work when the output has more than one item (e.g. for wood => 4 wood slabs)
