vtkm::io::reader::BOVDataSetReader creates delegation cycle

It looks like the BOVDataSetReader moved. When trying to compile the ContourTreeApp example I get a deprecation warning to use the BOVDataSetReader from its new location followed by an error, indicating that the constructor creates a delegation cycle.

I tried to update to the example to new reader, but unfortunately that resulted in linker errors:
