Refactor outcome. Move processes of outcome to separated files, and leave the outcome class as clean as possible.
Normal export in glb format is been fixed.
Ambient occlusion baker is been temporarily removed.
Many source file name and data type are prefixed by "skeleton" before, now all are refactored.
The class MeshResultContext represents the outcome of mesh generation before, now we have material, pose and animation, so we just rename it as Outcome.
This is an experiment test of animation clip generation. Mark leg and spine nodes to enable it or check it with the latest mosquito.ds3 example;
Skeleton offset is been fixed in this commit.
