Bug: Child Theme Theme Overrides

Hi,

I am using your plugin and have come across an issue. In src/Output.php line 184 you search for a wpp theme in the current theme directory using get_template_directory. However, in the instance where a child theme is being used, this will return the parent theme directory. Please update this to get_stylesheet_directory so I can use my own theme with your plugin.

Many thanks,
Jake.
