  -----------
  Alphabetically sort import statements and add comment explaining separation of `import yaml`

Sorting import statements was made easier and less error-prone using [isort](https://pypi.org/project/isort/)

Make it clear that the `yaml` package is not part of Python's Standard Library and should be installed with a package manager as outlined in [this](https://pep8.org/#imports) section of PEP8.
