migrate this to a cookiecutter template?

🚀 The feature, motivation and pitch

Instead of having a separate personalize.py, the entire personalization logic can be taken care of by cookiecutter. The size of the template will go down and it would become slightly cleaner.

There's already tons of cookiecutter Python package templates, so I'm not sure what that would add. One thing I like about this template repo is that it's a fully functioning Python package project even before running the personalization script. So even if people don't want to use this as a template, they can browse through it on GitHub and easily pull out the pieces they like. It seems like we'd loose that if we went with cookiecutter based on the look of audreyfeldroy/cookiecutter-pypackage.
