Use Hermite instead of Bezier for glTF spline interpolation

7

The cubic spline interpolation implementation in glTF animations wrongly uses Bezier splines instead of Hermite splines ([gltf 2.0 spec](https://registry.khronos.org/glTF/specs/2.0/glTF-2.0.html#interpolation-cubic), [Hermite Spline](https://en.wikipedia.org/w/index.php?title=Cubic_Hermite_spline)).
