Tint wool textures using white wool instead of actual wool colors.

Vanilla wool textures

As you can see, there are major differences between vanilla textures and the textures converted using SpriteCaster.

Start by reproducing SpriteCaster's resource-pack conversion with the wool textures shown in the issue, then compare the generated textures with the vanilla examples. The work is done when wool textures use white wool as the base for tinting rather than the actual wool colors and the resulting appearance matches the requested behavior.
