Changes to the Model API - IModelState now works with Optional. Handling of parts of the model is not optional, and coordinate space/result interpretation is up to the caller. IModel doesn't extend IModelPart by default anymore; MapModelState uses composition to achieve previous functionality, IModelPart implementations are disjoint now. Updated perspective handing to the new API, removed IPerspectiveState (MapModelState is now the same thing). Perspective transforms for the default fluid model.
Should replace all ad-hoc quad generation methods in forge, and make IBakedModel -> WorldRenderer data transfer faster. Added IVertexConsumer + helper classes; lighting that works correctly for non-axis-aligned faces using the new infrastructure. Changed smooth lighting algorithm, now it should work correctly for everything.
New block lighter can be disabled in the forge config options.
