Change the default compression level for PNG to 5.

The available range is 0..9. Recommendation from
'png_set_compression_level - Linux Standard Base' say 3..6 perform as
well as 9 and do considerably fewer calculations.

Fix vtkDataReader with signed char

The vtkDataWriter class uses the "signed_char" identifier for signed
char data but the vtkDataReader class only checks for "char". Now it
accepts either "char" or "signed_char".

This fixes VTK bug #13744.
