Different logo for dark mode

[elimae17]

Hi,

first of all, thank you for this awesome tool! You're doing a great job!

I think another cool thing to have would be the possibility to set a different logo for dark mode. My logo for example has a colored part and a black part. With dark mode enabled, one half of the logo disappears almost entirely into the background. I know I can disable dark mode in the CSS files of the theme or just upload an image with a white background, but it would be really nice if I could set a, let's say, completely white logo for dark mode so that my logo looks good either in light or dark mode. This might be a useful feature!
