Importlib ModuleNotFoundError python 3.7.0

[ben-edna]

dfetch uses importlib to find the reosurces in the package (template.yaml, schema).
Users with pythn 3.7.0 report:

ModuleNotFoundError: No module named 'importlib.resources'

When running dfetch nder python 3.7.0

importlib.resources should be part of 3.7.0, to be investigated.

Workaround is to install a newer version, python 3.7.9 is reported to work

[KrisEDNA]

Work-around (tested on python 3.6.5):

pip install importlib-resources
