please add font-family support

[PatrickHuetter]

I want to use font-family verdana for the text in my rendered pdf but the plugin doesn't recognize the css with font-family and the rendered pdf is with default font-family and serif.

It would be also fine if you would update the itext version.

@font-face {
font-family: 'Tahoma';
src: url(file:${System.env.HOME}/fonts/tahoma.ttf);
-fs-pdf-font-embed: embed;
-fs-pdf-font-encoding: Identity-H;
}
