[vtk] Add prototype of a vtk/vtp/vtu viewer
- Depends on vtk.js and itk.js
- Webpack configuration is injected using craco
- craco-itk and craco-vtk are plugins for craco
- test-vtk view shows some vtu data
- matrix grid output for simulation-2
- navigation and rendering is still to improve but this is a first prototype
