TODO before release

• Fix CSG rendering issues
• Check macOS version for code signature in CMakeLists.txt
• Use an environment variable to specify the default output option: ARTRAW or Spectral EXR.
• Address the double free when converting from ARTRAW to Spectral EXR (ArnSingleImageManipulationAction.m:802)
• Address the consistent colour shift in image conversion actions (clearly visible on gray images).
• Rename the actions (while keeping the current one for backward compatibility) to better describe they purpose.
• Bugblatter bug ? Suport OpenEXR ?
• Update version number in CMakeLists.txt.
