🐛 Fix pkgutil.iter_modules call

[KevinHock]

Give a list of str rather than a list of PosixPath

On Python 3.9.5:

>>> import email
>>> email.__path__
['/Users/kevinhock/.pyenv/versions/3.9.5/lib/python3.9/email']
>>> email.__path__[0]
'/Users/kevinhock/.pyenv/versions/3.9.5/lib/python3.9/email'
>>> type(email.__path__[0])
<class 'str'>

The pkgutil.iter_modules docs are pretty bad on this:
path should be either None or a list of paths to look for modules in.
it doesn't specify string.

You can see a lot of other OSS projects have had bugs like this:

• n1ngu/faker@c370176
• AttributeError: 'PosixPath' object has no attribute 'startswith' simongrest/farm-pin-crop-detection-challenge#2
  etc.

Stack trace for posterity was:

  File "/Users/kevinhock/.pyenv/versions/3.9.5/lib/python3.9/site-packages/parliament/__init__.py", line 69, in analyze_policy_string
    policy.analyze(

    for importer, name, _ in pkgutil.iter_modules(
  File "/Users/kevinhock/.pyenv/versions/3.9.5/lib/python3.9/pkgutil.py", line 130, in iter_modules
    for i in importers:

Hi @0xdabbad00, do you mind bumping the PyPI package with this change, whenever you get a chance? 👍🏼
