Allow configuration to include custom JS and CSS file(s)

[alienman5k]

It would be really helpful to allow users to be able to include their own JS files to add support to the previewer, one example I am thinking is to be able to render diagrams using something like mermaid.js

Maybe adding some configuration where we can include a list of JS files during the setup?

{
  md = {
    js = { 'file1.js', 'file2.js' }
  },
  asciidoc = {
    js = { 'file1.js', 'file2.js' }
  }
}

With the latest update, you can now embed html in markdown, which allow you to use external js and css files, as long as they are in server root (run :chechhealth livepreview to see path to server root, by default it is :pwd).

I know it is not exactly what you want, but I hope that give you a workaround way.
