Take wrist init rotation into consideration

[henryouly]

In SeedAvatarStudio scene setup, the result from ComputeWristRotation should be further rotated using Quaternion.Euler(-90, 90, 0). There has to be a better way to consider the coordinate difference in model setup.

@superkudo You can also consider taking this issue. Thanks.
