* exiftool: Add "-gps*=" removal example
A common use of exiftool is removing location data from photos. One may wish to preserve most EXIF data (ex. rotation, date/time taken, etc.) but remove private location data. This example accomplishes this common task.
The proposed example comes from exiftool's author, Phil Harvey:

This example works to not only remove GPS data from EXIF but also from Adobe's XMP tags.
Tested with JPEG and HEIC photos using exiftool 12.50.
