Windswept glacier

In the snowy biome, it replaces the formation of Windswept hills, Windswept forest and Windswept gravellyhills. The squares on the rock layer mainly produce Packed Ice, and sometimes blue ice clusters. If Windswept hills, Windswept forests and Windswept gravel hills are formed in snowy, it's strange that it will rain where there is no snow in the snow, so it's necessary to introduce Windswept glacier biome.
