Displacement maps big update

[TheShuEd]

About the PR

The displacement maps is a very powerful tool that is not fully integrated into the game. This pr is making some changes, making it easier to use and expanding its capabilities.

• The function of applying the displacement map is put into a separate system, and is easy to reuse at different points in the game.
• You no longer need to write a bunch of parameters passed to the shader every time.
• added support for maps of different sizes. A 32x32 or 48x48 or 64x64 (or any other) resolution, if created, can now be modified with a corresponding displacement maps of the same size via prototypes.
• clothing that uses special species clothing sprites will ignore displacement maps, favoring hand-drawn sprites.
• inhand item sprites got support for displacement maps (not used anywhere, but verified in my fork that it works)
• Removed stencil masks, and replaced with displacement maps for the different genders of the species. (the map is better than the mask in all parameters, and now the system works for any layers, not just uniforms)
• added shoes and ears voxes displacement maps

Breaking changes

the format for describing displacement maps in the species prototypes has been changed:
from

    displacements:
      jumpsuit:
        layer:
          sprite: Mobs/Species/Vox/displacement.rsi
          state: jumpsuit
          copyToShaderParameters:
            # Value required, provide a dummy. Gets overridden when applied.
            layerKey: dummy
            parameterTexture: displacementMap
            parameterUV: displacementUV

to

    displacements:
      jumpsuit:
        sizeMaps:
          32:
            sprite: Mobs/Species/Vox/displacement.rsi
            state: jumpsuit
