Documentation: -ImageDataHash option is missing

[olegos]

The -ImageDataHash option seems to be missing from the documentation... Please add it, thanks!

ImageDataHash isn't an option, it's a tag, and appears on the Extra Tags page.

Tags can be copied to other tags. Options control how exiftool operates.

I see, thank you! I did search in the ExifTool Tag Names page, in addition to the main "Application Documentation" page, but hadn't realized that it only listed links to sub-pages. A search option for all of documentation pages would surely be useful...
