Data Packs: Modify/Add Potion Recipes and NBT Support

Just as players can add shapeless crafting, shaped crafting, smelting, blasting recipes (etcetera) using data packs, we should also be able to add recipes that work in brewing stands. A simple addition such as this will open many doors for data pack creators, and would fit well with the possibilities that already exist with data packs.

The JSON file for a brewing recipe could look very similar to the "smithing" recipe type. I used a basic "withering potion" idea I had with the wither rose an ingredient being added to an awkward potion:

{
  "type": "minecraft:brewing",
  "addition": {
    "item": "minecraft:wither_rose"
  },
  "base": {
    "item": "minecraft:awkward_potion"
  },
  "result": {
    "item": "minecraft:potion{nbt}"
  }
}

This of course would require NBT support for items in data packs, which I would imagine could behave similarly to how NBT data is added to items acquired with the "give" command.
