Downscaled Ghasts

A pack that downscales the Ghast and Happy Ghast to a 16x16 face size.

Faithful Version

This addapts the 1.21.6 ghast texture changes to the old resolution, particularly noticable on the bottom of the ghast texture.

Retro Version

This directly backports the old ghast texture from pre-1.21.6, as well as making the happy ghast align with said texture.
