ENH: Add SCIFIOImageIO.

This package provides an ITK ImageIO plugin that uses SCIFIO
to read and write supported life sciences file formats.

The SCIFIO ImageIO plugin was developed by Gaetan Lehmann, Mark Hiner,
Curtis Rueden, Melissa Linkert and Matt McCormick. Development of this
module was funded in part by the [FARSIGHT
project](http://farsight-toolkit.org/), as well as the [Open Microscopy
Environment](http://openmicroscopy.org/).

Special thanks to Alex Gouaillard, Sebastien Barre, Luis Ibanez and
Jim Miller for fixes and suggestions.

For further details, including usage instructions, see the [Bio-Formats
ITK page](http://openmicroscopy.org/site/support/bio-formats/users/itk).

Please [direct any questions to the OME
team](http://www.openmicroscopy.org/site/community).

To build the module, set

  Fetch_SCIFIO to ON in the ITK CMake configuration.
