glTF2: import correct animation values for CUBICSPLINE 

CUBICSPLINE interpolation has tangent values with the animation data.
Current import don't care this interpolation type but it will help not
to fetch tangent values instead of animation data.

Note: Assimp cannot support interpolation types yet.
