Move wall png's to another location

[delta-atk]

When downloading the repo it takes ~50 MB of disk space atm, of which >46 MB are wall0/1/2.png in assets/install. I always have problems cloning the repo as it fails multiple times and takes forever, which is especially bad when updating hyprpm. I think it would be great to move the files elsewhere to bring down the size to a few MB
