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