New mob from mob vote in winter drop

The Iceologer would spawn during raids on winter villages.
It would drop an icy trident, which, when thrown at an enemy, would immobilize them, granting them a level 4 slow and freezing them as if they were in powdery snow. The trident itself could have a few new enchantments, but the existing ones would only work with more general ones, such as mending and umbreaking, Loyalty, Piercing, and Torpedo. Upon attempting to strike, the torpedo would activate and, upon hitting the enemy, freeze them.
