Version of Six causing warnings in python 3.11

[dahlend]

I've been having a few issues using python 3.10/3.11 with this package due to the older version of the Six package which appears to be copied into the Extern folder.

See the discussion here: benjaminp/six#341

Specifically the newer versions of Six have this: https://github.com/benjaminp/six/blob/master/six.py#L194 to be defined.

Potential solutions:

• Update this six.py file
• Update the package installation method so that pip will automatically grab the latest package versions instead of having an extern folder.
• Remove support for python 2?

Thank you for reporting. Looks like there are some tests that are breaking, though probably unrelated. Let me look into it.
