Add images download path to config

[NikMAX2077]

It will be convenient to have ability to set image download directory in config file and via GUI. Than auto generated unit will have comand like
/usr/bin/python3 /home/username/.local/share/pipx/venvs/liewa/lib/python3.12/site-packages/cli.py -o /Images/Wallpapers/liewa
instead of
/usr/bin/python3 /home/username/.local/share/pipx/venvs/liewa/lib/python3.12/site-packages/cli.py

The cli actually has a -o flag for saving all downloaded images. Or do you mean a path to the "composite" bg image?

I mean it will be nice to have option to set both -o parameter and composite image with GUI too, not in CLI only
