Recipe format

The recipe format, as currently used in mineflayer.

{ // dictionary of ID -> recipes for that ID
	"<result ID>": [ // list of recipes
		{ // one recipe to get an item with ID <result ID>
			"type": "<result ID>"
			"metadata": "<result damage>",
			"count": "<result amount>",
			"inShape": [ // the crafting grid, list of rows
				[ // one row of the crafting grid
					"<A1>",
					"<A2>",
					"<A3>"
				], [
					"<B1>",
					"<B2>",
					"<B3>"
				], [
					"<C1>",
					"<C2>",
					"<C3>"
				]
			],
			"outShape": ["..."] // optional, same as inShape,
			                    // but the items that remain
			                    // in the grid after crafting
		},
		{ // another recipe for the same ID, but maybe different meta
			"type": "<result ID>"
			"metadata": "<result damage>",
			"count": "<result amount>",
			"ingredients": [ // list of ingredients
				{
					"id": "<ingredient ID>",
					"metadata": "<ingredient damage>" // optional
				}
			],
		},
		{ // another recipe for the same ID, may be for different meta
		// ...
		}
	],
}

The crafting grid looks like this:

A1 A2 A3
B1 B2 B3
C1 C2 C3

When the required grid is smaller, empty rows/cells may be omitted:

A1 A2

would be "inShape": [["A1", "A2"]],

A1
B1

would be "inShape": [["A1"], ["B1"]],

The numbers (A1 to C3) in inShape are the required item's ID, or null if empty.

result ID is duplicated for convenience.
