Fix Indium incompatibility

[BluSpring]

Issues: #185, #212

This PR creates a mixin into Indium's TerrainRenderContext#bufferQuad, making the quad light also use LDL's lightmap values, which solves both:

• flat side of doors and hoppers not dynamically lighting (Top of hopper is not lighted up when mod Continuity is installed #185)
• flat lighting not working (lighting not working on full blocks #199?)

With the nature of how this mixin works, it unfortunately requires a compile-time dependency on Indium, unless someone can figure out a way to avoid that entirely.
