Set Image path from executable file (Image Module)

[kpanuragh]

I just made a small tweak in the image module to get the image path from an executable file. Here is a sample configuration.

 "image/album-art": {
	  "exec":"~/.config/waybar/custom/spotify/album_art.sh",
	  "size": 32,
	  "interval": 5,  
    },

If there is a path config exist, then it will load the image from the path config; otherwise, it will check for an exec configuration and execute the script, which should return a file path, and then it will load the image.
Here is a simple executable file

#!/bin/bash
album_art=$(playerctl -p spotify metadata mpris:artUrl)
if [[ -z $album_art ]] 
then
   # spotify is dead, we should die to.
   exit
fi
curl -s  "${album_art}" --output "/tmp/cover.jpeg"
echo "/tmp/cover.jpeg"
