Add multiple matching Stacks

[forester302]

Make RecipeDataGenerator for 1.20.5 add multiple recipes to an item when there are multiple matching stacks for a slot

Minecraft uses a tag system to do this as if there are 9 slots with 5 options each that becomes 1953125 recipes

I have compromised on this and in cases where there are options i have only done 1 recipe for each option
(for example crafting tables, it does 10 recipes - 1 for each wood type - instead of the 10000 possible ways to craft a crafting table)

this should be enough to fix the issue in PrismarineJS/minecraft-data#917, but not every way you can make an item is represented, and wont be unless a tag system can be implemented into this also.

This only accounts for multiple stacks in shaped recipes. We can use this method for shapeless recipes:

private void generateShapelessRecipe(DynamicRegistryManager registryManager, JsonObject finalObj, ShapelessRecipe sl, int n) {
    boolean hasIncremented = false;
    List<Ingredient> ingredients = sl.getIngredients();
    List<Integer> ingr = new ArrayList<>();

    for (Ingredient ingredient : ingredients) {
        var matching = ingredient.getMatchingStacks();

        if (matching.length > n) {
            ingr.add(getRawIdFor(matching[n].getItem()));
        } else {
            ingr.add(getRawIdFor(matching[0].getItem()));
        }

        if (matching.length - 1 > n && !hasIncremented) {
            generateShapelessRecipe(registryManager, finalObj, sl, n + 1);
            hasIncremented = true;
        }
    }

    JsonArray ingredientsArray = new JsonArray();
    for (Integer id : ingr) {
        ingredientsArray.add(id);
    }

    JsonObject finalRecipe = new JsonObject();
    finalRecipe.add("ingredients", ingredientsArray);

    JsonObject resultObject = new JsonObject();
    resultObject.addProperty("id", getRawIdFor(sl.getResult(registryManager).getItem()));
    resultObject.addProperty("count", sl.getResult(registryManager).getCount());
    finalRecipe.add("result", resultObject);

    String id = ((Integer) getRawIdFor(sl.getResult(registryManager).getItem())).toString();

    if (!finalObj.has(id)) {
        finalObj.add(id, new JsonArray());
    }
    finalObj.get(id).getAsJsonArray().add(finalRecipe);
}

Then in generateDataJson():

...
} else if (recipe instanceof ShapelessRecipe sl) {
    generateShapelessRecipe(registryManager, finalObj, sl, 0);
}
...
