New pale varients, mangrove and beach update.

A pale forest variant with tall singular wide trunk wood trees. Scary things spawn in this biome. The tree skither, a creature that lurches onto leaves and dead tree canopies. Stares at you from above and attacks you if you go near the tree, reaching its paw white long arm down, its glowing orange eyes but the creature it self is completely pale or light gray. Tagrins are white or gray troll like creatures that spit toxic green goo at you from a distance but can hit you if you get close, the larger one spawns in the pale swamp and physical hits do more damage but it is slower to walk. Also add mangrove roots creatures that are black, and mojang should also make it so that skeletons and creeps cannot spawn in a mangrove biome, but the mossy drowne and moss zombies spawn instead of normal zombies. Crabs can also spawn in mangroves, still able to drop the crab claw from the mob vote, the can also drop crab meat. Small and large crabs, only large can drop claws. Add shells to beaches, and oysters on stone beaches and water edges, if you walk on the oysters they damage you. Basically adds oyster patches which are places like sculk growth patches that sit on top of blocks , as in it can be on top or on the side of blocks connected access them. Oysters should also be farmable, adding a new water farming feature. A dark yellow beach biome should be added with palm trees, also in oasis that can spawn in the desert as a generation feature.
