fix: remove swww deprecation warning

The usage of swww init instead of swww-daemon was causing a deprecation
warning to appear "DEPRECATION WARNING: `swww init` IS
DEPRECATED. Call `swww-daemon` directly instead".

`swww init` was depricated in version 0.9.0 of swww
but `swww-daemon` was added back in version 0.7.0.

This fixes issue #39
