Update Panasonic EXIF Information
Based on the information available at  and based on the output of the images of my Panasonic Lumix DMC-G6, I wrote a patch for exiv2 updating the tags that I know of.
The second patch gets rid of a few duplicate entries which I'm not sure why they would be necessary, I can't see it.
Note that I broke compatibility with a few older cameras, since Panasonic doesn't seem to care too much about backwards compatibility (i.e. contrast mode entry), but I thought it would be better to stick to current models rather than antique ones.
