pyYAML Load Error

[dr00b]

Updated versions of pyYAML no longer allow calling load_all as on line 32 for d["Direction"])) for d in yaml.load_all(f0)]

With pyyaml version 6.0, I was able to run by changing to safe_load_all

I would consider setting minimum version requirement for PyYAML, as it appears the change patches a vulnerability.
