/**
 * Filter for script type
 * $type (string) can be swift/javascript or swift/lazyscript (swift/lazyscript will run only user interaction, while swift/javascript will be executed immediately after higher priority assets has been processed)
 * $tag (Swift3_HTML_Tag) this is a Swift3 HTML Tag object, it has $attributes(array), $outer_html(string) and $inner_html(string) properties, what you can use to identify scripts
