Flowgraphy: Wetter

This update spends quite a bit of time looking at the sky. Until last month, I was fairly sure AI was not better than me at shader programming. Now I am not completely sure. So the sky colors have been tuned in a more physically grounded way. Sunsets now feel more natural and beautiful. The app also renders the sky at night, improving dawn and nighttime skies. It even accounts for how ozone in the atmosphere changes sunset colors. I also added a 3-day aurora forecast and aurora rendering. The timing is a little funny: many northern aurora spots are in midnight-sun season right now. I added auroras, and then the sky forgot to get dark. When winter comes, try opening the app around Tromsø, Norway. By then, the auroras should finally have a shift to work. While checking Tromsø, I also found that the midnight-sun rendering looked a bit awkward, so I fixed that too. Polar skies where the sun and moon appear together should now feel a little more natural. I also fixed wind speed units in parts of Europe, where m/s was shown instead of km/h. Thank you to the user who reported it. Thanks as always to everyone using Flowgraphy Weather. I will keep updating it in spare moments between household chores.
