Basic HMD MIMe joint animation support

[trigger-segfault]

• Added basic support for HMD MIMe Joint and RPY (Roll Pitch Yaw) animations. Added notes for MIMe Vertex Normal about what is incorrect.
• Changed some HMD header parsing to treat more values as optional. For example, coordTop was missing from NonShared(?) header once.
• Added helper function to print HMD animation interpolation types used in an instruction set.
• Added Limits.MaxTMDVertices for use with TMDParser NVert and NNormal.
• AnimationBatch.SetTimeToFrame now defaults to setting the time to the start of the frame, but has an optional parameter to use the end of the frame instead.
• Added GeomMath.Snap double x overload.
• Removed leftover function call in GeomMath that was only used to look up references in Visual Studio.
