Is your feature request related to a problem? Please describe.
F3D now support opening QuakeMDL files and animating them, however frames are not interpolated, which may may provide nicer rendering and also be a good analysis tool for users.

Describe the solution you'd like

• Add frame interpolation code in MDL importer using standard VTK tools
• Add a flag setter in the importer to control this behavior
• Add a QuakeMDL reader option to control if frame should be interpolated or not
• Add tests
