feat: Update for modern python (#158)

* feat: Update for modern python

This updates things to use more modern python practices.
This includes:
* Adding a pyproject.toml file
* Add type hints

**BREAKING CHANGE**
`Webpusher.encode` will now return a `NoData` exception if no data is
present to encode. Chances are you probably won't be impacted by this
change since most push messages contain data, but one never knows.
This alters the prior behavior where it would return `None`.

Includes fixes from #152 by https://github.com/TobeTek (Thanks!)
