Minify inline Javascript

[toxpal]

I used https://github.com/nochso/html-compress-twig for years which worked great, but it doesn't support Twig 3 and is not maintained anymore, so I switched to HtmlMin for Twig. Migration was easy and it works perfectly, but I really miss inline Javascript minification.

According to #42 it looks such option is kind of supported? Would it be possible to minify inline JS in next release of HtmlMin?
