Windows wallpaper

[Davido264]

Hi there, I was working with the pywal module to make a plugin for another app, and i found that (at least in my pc) SystemParametersInfoA doesn't work, but SystemParametersInfoW does. My pc es 64 bit architecture, and acording to the logic in pywal.wallpaper.set_win_wallpaper(), SystemParametersInfoA should work. I'm not confident enough to make a pull request deleting that if statement (although it is simple lol). I think I am doing something wrong or is an isolated case, so I mainly invite to research over this case
