SE installation error

A fresh installation of ScriptEngine 0.12.3 from PyPI yields

The issue is that scriptengine/yaml is not found by setuptools.find_packages() because it has no __init__.py. Thus, scriptengine.yaml is not packaged in the PyPI package.

The secondary issue is that the automatic testing always install from sources and therefore not catching the problem. Need to add a github action that installs from PyPI.
