AFAICT you are using the python requests library [here](https://github.com/clearbit/clearbit-python/blob/master/clearbit/resource.py#L46) without specifying any [timeouts](http://docs.python-requests.org/en/latest/user/quickstart/#timeouts). The docs state that _If no timeout is specified explicitly, requests do not time out._ Can you add an API method with the timeout as a parameter please?
