Windows build failing

[VIPQualityPost]

Hi,

I installed on macos, it works fine. I tried to install on my work windows machine today, and am unable to generate even demo examples from repo:

metadata = Metadata(**yaml_data.get('metadata', {})),
AttributeError: 'NoneType' object has no attribute 'get'

This was with demo02.yml from the repo.

@VIPQualityPost - thank's for reporting this error, but please provide information about your set of versions as described in CONTRIBUTING.md and how you installed WireViz and dependencies. Otherwise, it might be hard to help you when nobody knows how to recreate the error you report.
