Updated Sea Shores

Seashores/beaches aren't really a thing in minecraft, but they could be. they could add wave sounds. They could also add treasure beaches, where you could sift through sound and get trash items like leather or sticks, but also medium rare items like gold and iron, then rare items, and i mean really rare items, like diamonds and heart of the sea. These treasure beaches would be fairly rare as well, and not all sand there would hold treasure.
