Fix: with this you can use ~ (user home) without absolut path

[pepe-el-pepe]

i don't have any experience in python coding but after a little i found out changing this line

https://github.com/Arxari/apod-hyprpaper/blob/90346958f3c2be41f0bf90c292b57cb72d88b392/apod.py#L10

into:

WALLPAPER_DIR = os.path.expanduser("~/Pictures/apod")

it will work

cheers
