Release Seshat API package on pip

[edwardchalstrey1]

This will make it easier to install in Python environments used for Seshat projects and also if other users wish to work with the data.

• Make a release on GitHub
• PENDING: Create an org on PyPi
  • This is pending for ages - Nathan mentioned that the ATI org never got approved so may be pointless
• Follow this guide to properly package and upload to PyPI
• We can then include seshat_api as one of the requirements for the examples python env

Is this needed to push the package to PyPI? Otherwise, I say, let's just go for it, and skip that step :)

Should also automatic testing post-build (detailed unit tests would be nice but that's a topic of its own)
