New Command Line Flag for tags or comments

Hi Team,

We would like to add a tag "compressed" after the image is compressed, and also have guetzli to check the tag, if it contains specific "compressed", it will ignore the images without compressed it again? Can this be done easily? Thank you very much in advance

I wrote a tool which does just that. https://github.com/romainmenke/simple-guetzli

@romainmenke's tool is brilliant, and records progress in a log file.

If you're asking for this tag to be recorded in an image's EXIF data, guetzli currently strips EXIF data. Patch #175 has been submitted to add the option of preserving EXIF, and this would probably need to be merged before EXIF tagging would be an option.

I see the wisdom of both approaches. For my personal use case, an EXIF tag would work better.

@romainmenke @mgrhm. Thank you very much for your help. I would like to have a command line flag to add EXIF tag.
