tiles are changed when they shouldn't be

Hi! For some reason, aoc_tiles keeps regenerating tiles for the days that weren't changed at all, which floods my commits with unnecessary files. See this commit, for example. I don't quite understand why it picks these specific files and not the others.

I suspect that switching to a different OS is what triggers the issue. I made several commits from Windows and no extra images were changed. Initially I was switching between Linux and Windows.

That's weird. It seems like the second number of the day is shifted by 1 pixel in each image. There is probably some library which renders the fonts in pillow slightly differently depending on which OS it is. Not sure how to solve it yet, I'll look into it
