v0.5.6:

- **BUGFIX:** fix A4 and A5 paper sizes in inches for **chrome-headless**:
  it's not 8.5 x 11.0 (US letter) but 8.26772 x 11.695 (DIN A4), the former
  being chrome-headless defaults. This is important if you want to create
  proper A4 pages
- Users printing **US letter** sized PDFs, please use `page_size: :letter`

      more fashionable and extensible error messages. Extensible towards new
      generators.

      `chrome-headless-render-pdf`

update description

Got rid of misc_random dependency. This was here to manage between

      depreciated random functions in Erlang. We go ahead using plain
      `Enum.random/1` instead, implementing our own
      `PdfGenerator.Random.string/1` function. This also removes a common
      pitfall when drafting a release with distillery.
      * Thanks to [Hugo Maia Vieira](https://github.com/hugomaiavieira) for this
        contribution!
      * Since `Enum.random/1` is only available since September 2015 (three
        years ago) I am OK with raising the minimum Elixir version to v1.1 –
        Since this may break projects still running on Elixir v1.0
        **I bumped the version to 0.4.0***.
