Installs the final path-image handler in a Phoenix router.

Import this module and call og_ex_routes/1 after all application routes:

defmodule MyAppWeb.Router do
  use MyAppWeb, :router
  import OgEx.Router

  scope "/", MyAppWeb do
    pipe_through :browser
    get "/posts/:id", PostController, :show
  end

  og_ex_routes()
end

Use either this router integration or plug OgEx, router: MyAppWeb.Router in the endpoint. Do not install both.
