Country flag of Switzerland is squeezed

[by]

The original country flag from https://dynamospanish.com/flags/countries/switzerland/ is square (as it should be); at https://github.com/flightaware/dump1090/blob/master/public_html/flags-tiny/Switzerland.png and https://github.com/flightaware/dump1090/blob/master/public_html_merged/flags-tiny/Switzerland.png, it is stretched to the rectangular format of the other flags

The original is actually not square (see the topmost "tiny" flag, which is what we use):

If you have a better version with the correct aspect ratio (it would need to still be a rectangular image of the same size, with transparency at the left/right edges), could you provide the new image or a PR updating it?
