Allow opj_compress and opj_decompress to read/write images over stdin/stdout

[gcode-importer]

Originally reported on Google Code with ID 379

I would like to provide input to opj_compress and opj_decompress over stdin. This allows
me to pipe images in to these tools without needing to write temporary files to disc
and incurring the performance overhead that comes with. Similarly, I would like to
get the output of these tools over stdout, again, to avoid writing temporary files
to disc.

This is a feature already available in tools like ImageMagick and libjpeg.
