Wandering traders selling sponges

Wandering traders could sell dry sponges for 5 emeralds, which is a fair and balanced price for a block that can completely drain massive bodies of water.

Additionally, this feature getting added would also solve a pretty big problem: Sponges are currently non-renewable, tedious to obtain, and can only be found in Ocean Monuments. We wouldn't have to literally risk our lives just to get one. Ocean Monuments are already extremely rare too, and c'mon, it's just a sponge 😄

Finally, it would be very handy for Skyblock and Superflat players who don't have access to Ocean Monuments.
