COPY STEALTH PNG INFO TO EAGLE NOTES FIELD

Notes: Eagle must be running with the library the files belong to open when you run this script, otherwise Eagle will overwrite your changes to the sidecar .json files upon next launch. This script will not work on files uploaded to websites/platforms that strip metadata out of images, since it relies on reading and copying Exif data.
