Decrease priority to load last the wp_head hook

I had to update the priority to load later the wp_head hook you have on file “multiple-domain-mapping-on-single-site\multidomainmapping.php” line 94 from 20 to 100
to this:
add_action('wp_head', array( $this, 'output_custom_head_code' ), 100);

I need this to load a custom favicon + scripts last and the current priority loads it to early not allowing to change the favicon on different domains.

Can you please update to plugin to this? as each update I need to update this? or create a custom filter to edit this?
