Sort images by aspect ratio

This script does not care if image is in portrait or landscape ratio. Useful for sorting before developing your pictures.
Did you use it? ⭐ it!

What this should do:

• find all files in inputDir
• run exiftool on all files to find sizes (you need to have this installed)
• copy files to new directory, prefixed by aspect ratio value (ex: ./output/0.67/yourfile.jpg)

And it is using parallel processing, just because I can.

Example output:

Number of processors:  8
Files to process:    342
Output directory: ./output
