Dependency on: [html-minifier](https://github.com/kangax/html-minifier) version 3.x makes it impossible to fix some bugs, such as [minifyJS not working](https://github.com/kangax/html-minifier/issues/999). I suggest archiving this seemingly dead repository and moving to a minify-terser based fork, such as: [gulp-html-minifier-terser](https://github.com/pioug/gulp-html-minifier-terser).
