Add ‘flags’ (coat of arms) for the Norwegian counties

The images were downloaded from the Wikipedia page
https://no.wikipedia.org/wiki/Fylkesv%C3%A5pen_i_Norge
on 2018-08-27. They were then converted to PNG
files with a common height (200 pixels).

Note that the images at Wikipedia have been improved
over time, so the KGeography images should probably
also be updated in the future.
