Luish's Guns Crafting Add-on

Simple add-on that makes weapons from the [Luish's Guns mod/datapack](https://modrinth.com/datapack/luishs-guns) craftable. ### Rifle Crafting  ### Shotgun Crafting  ### Double-Barreled Shotgun Crafting  ## Why a separate add-on and not included within the mod/datapack itself? Crafting may be slightly broken from a survival-friendly experience. Additionally, because it's based on a datapack, crafting can't be modular within the original datapack/mod. Furthermore, the creator's original plans were to make a special crafting table for weapons, which development has been delayed over time and could not be included in the original project.
