VTK.JS not implement LINEAR and CUBIC in ImageReslice.

The image generated by NEAREST will have obvious jaggedness and the effect is not good.

This would be a good feature to add. Pinging @finetjul, since he worked on ImageReslice.

Yes, the LINEAR and CUBIC can be implemented similarly to the NEAREST.

I looked at how it is done in [VTK (C++)](https://github.com/Kitware/VTK/blob/master/Imaging/Core/vtkImageReslice.cxx) and wrote it in JavaScript for VTK.JS

Feel free to do the same for the other interpolation.
