Shared boundary studio updates

[iyerkrithika21]

As per #1235 the following features/changes are required for studio:

• [ ] Detecting if an input file is contour. Currently the number of points in the first cell of the polydata here and here are checked
• [x] MeshWarp should not crash if its a contour domain. (related to #1291 ? )
• [x] Option to toggle opacity in Studio (Is this related to #1452 ?)
• [ ] Options to enable shared boundary and set the weighting across domains in studio #1780

Need discuss how to include these options in the XML file? - Enable shared boundary and set the weighting across domains in studio https://github.com/SCIInstitute/ShapeWorks/blob/a36280296d137a9c40034fd18a50ffa99e4803e8/Libs/Optimize/OptimizeParameters.cpp#L227 - Option to toggle opacity in Studio. hardcoded here: https://github.com/SCIInstitute/ShapeWorks/blob/a36280296d137a9c40034fd18a50ffa99e4803e8/Libs/Optimize/OptimizeParameters.cpp#L227

My plan to support contours is to make them explicit in the spreadsheet ("contour_*"), so you would have something like this:

shape_part1	shape_part2	contour_boundary
1a.vtk	1b.vtk	1boundary.vtk
2a.vtk	2b.vtk	2boundary.vtk
3a.vtk	3b.vtk	3boundary.vtk

This is somewhat separate from the shared boundary since we can support contours directly.

How are we generating the shared boundaries?

[iyerkrithika21]

The shared boundary is also a mesh. So the project file has 4 input columns: left_mesh(vtk), right_mesh(vtk),shared_surface_mesh(vtk), boundary_contour(vtp).
