Updated the image reader classes to better follow VTK-m naming convention (i.e. use `ImageReaderPNG` instead of `PNGReader`). The structure of the image reader class now also better matches the interface for the VTK reader. Also put the implementation of the image readers into the `vtkm_io` library so that it only has to be compiled once.
