Unable to connect to oguri socket: No such file or directory

[I60R]

This is displayed when spawning swayblur when oguri daemon isn't run. Maybe it would be better to spawn a new instance instead of printing the error?

Also, it seems that currently oguri conflicts with swaybg and it's a bit of a puzzle to figure this out, especially if the latter is launched through setting wallpaper in sway config. Although, it's not directly related to swayblur it could be handled here (by killing swaybg process) until it gets fixed upstream

I'll add a section to this in the readme, but instead of having the line in your sway config setting the wallpaper it expects you to start the oguri daemon. I'll make that more clear and spawn an instance instead though
