split out version into it's own module

[mattrasmus]

Thanks for submitting this PR. Can you also update setup.py to find the version correctly?

The test error is due to a recent change in an upstream dependency (aibotocore vs botocore) and is unrelated to the current PR. I'll investigate the dependency issue separately.

Thanks!
