Run async driver

[douglasdcm]

Hi, how are you? I know there is an example of asynchronous calls using Beautiful Soup and requests, but I'd like to add other one using a library I've been working for. It is similar to Selenium or Arsenic. I'm sending this PR just to show you an example of the implementation using this library. If you think it doesn't match the purpose of the repository, feel free to ignore/reject it :)

If you want to test the PR, check the instructions in Python file I'm uploading in this MR, please. Thank you!
