Wandering traders have unused Age and ForcedAge tags

Wandering Traders have unused Age and ForcedAge tags. Most likely because their model, texture, and NBT data was copied from villagers. Side note: these tags are always valued at 0. If you change them, they instantly change back to 0. Why have these tags if: first off, there's no such thing as a baby wandering trader. Secondly, they are reset to 0 every tick, causing minor(depending on how many you spawned) performance issues.
