ENH: BinaryMathematicalMorphology baseline testing

This enables baseline testing for the BinaryMathematicalMorphology
module. This specifically does the following:

- Defines OutputBaseline for all baseline tests in Filtering/BinaryMathematicalMorphology/CMakeLists.txt
- Implements ITK's WriteImage function for ClosingBinaryImage, OpenBinaryImage and PruneBinaryImage.
- Saves new baseline images for ClosingBinaryImage, OpenBinaryImage, and
  PruneBinaryIamge.
- Changes original output ClosingBinaryImage.png, OpenBinaryImage.png and
  PruneBinaryImage.png to clarify these are outputs in the QuickView
window.
- Allow user to define input and output file paths for
  ClosingBinaryImage, OpenBinaryImage, PruneBinaryImage.
