Issues with Dynamic Credentials example

[danielperez660]

In the documentation we see the example of

>>> from requests_aws4auth import AWS4Auth
>>> from botocore.session import Session
>>> credentials = Session().get_credentials()
>>> auth = AWS4Auth(region='eu-west-1', service='es',
                    refreshable_credentials=credentials)
...

under the "Dynamic STS Credentials using botocore RefreshableCredentials" section.
This seems to be a defacto need for long running applications.
However, on running this fragment of code, we see the error:

raise TypeError(msg)
TypeError: AWS4Auth() takes 2, 4 or 5 arguments, 0 given

The implementation of dynamic credentials on my end is a direct copy and paste of the example given on the wiki so I don't understand where the issue is stemming from.

Not only am I an idiot, but also a fool and a buffoon. I was running a version of AWS4auth which was SEVERELY outdated. Ignore anything else I say.
