Percy's Sewing Kit

Changes:

• Improved performance.
• Updated to Minecraft 1.21.7.
• Changed versioning to reflect the Minecraft version more clearly, since this datapack is heavily dependant on Minecraft versions. In the case of this version, 1.21.7V1, "1.21.7" refers to the Minecraft version, "V1" represents the datapack version, and will go back to 1 every Minecraft update.
