PDF generation!

> So weird that it's still a thing for murderers in horror movies to keep clippings of their crimes. PDF that shit!

What started out as a wrapper for the Erlang [erlguten](https://github.com/ztmr/erlguten) library has turned into a full rewrite in Elixir.

## Plan

Rewriting the basic PDF functionality means:

- [x] text
- [x] fonts
- [x] images
- [x] rendering/exporting
- [ ] parsing existing PDFs
- [ ] templating
- [ ] documentation

# Usage

```elixir
  # Load image, get alias
  {alpaca_alias, alpaca_rendition} = Gutenex.PDF.Images.load("./test/support/images/alpaca.png")

  {:ok, pid} = Gutenex.start_link
  Gutenex.add_image(pid, alpaca_alias, alpaca_rendition)
    |> Gutenex.begin_text
    |> Gutenex.set_font("Helvetica", 48)
    |> Gutenex.text_position(40, 180)
    |> Gutenex.text_render_mode(:fill)
    |> Gutenex.write_text("ABC")
    |> Gutenex.set_font("Courier", 32)
    |> Gutenex.text_render_mode(:stroke)
    |> Gutenex.write_text("xyz")
    |> Gutenex.end_text
    |> Gutenex.move_to(400, 20)
    |> Gutenex.draw_image(alpaca_alias, %{
      translate_x: 300,
      translate_y: 500,
    })
    |> Gutenex.export("./tmp/alpaca.pdf")
    |> Gutenex.stop
```

Now open up that file and you should see some text near the bottom and a picture
of what I believe to be an alpaca. Could also be a llama.
