Use Asciidoctor PDF (JS) as a dependency

[ggrossetie]

This project was initiated as a fork of Asciidoctor PDF (JS) because (I believe that) at the time there was no release.
Since then the project is now more stable and I think we should use Asciidoctor PDF as a dependency:

$ npm i -g asciidoctor asciidoctor-pdf

It would allow to remove a lot of code 💥

humm yes it might work, the good thing about how it is now it is that it is self-contained, on the other way you need to have everything installed to make it work. But yes maybe it could be a good next step.

Currently, you still need to run npm i to install the dependencies before you can use ./bin/asciidoctor-pdf.

But yes maybe it could be a good next step.
