Remove SMTK plugins from packaging
Some sessions were allowing unsupported file types (STL files) to be loaded, causing confusion when aeva operations did not work.
aeva should not package
- mesh-session,
- polygon-session,
- vtk-session, or
- oscillator-session plugins.
@tjcorona We may also want to keep the mesh (not mesh-session) plugin from registering reader support for some filetypes. Is there an easy way to do this?
