Stacktrace for a given requirement file

Pipenv: 2023.6.26
Python-inspector 0.9.6

I have the following file, generated from `pipenv`:

```
-i https://pypi.org/simple
anytree==2.8.0
attrs==21.4.0 ; python_version >= '2.7' and python_version not in '3.0, 3.1, 3.2, 3.3, 3.4'
iniconfig==1.1.1
jinja2==3.1.2
markupsafe==2.1.1 ; python_version >= '3.7'
packaging==21.3 ; python_version >= '3.6'
pluggy==1.0.0 ; python_version >= '3.6'
py==1.11.0 ; python_version >= '2.7' and python_version not in '3.0, 3.1, 3.2, 3.3, 3.4'
pyparsing==3.0.9 ; python_full_version >= '3.6.8'

tomli==2.0.1 ; python_version >= '3.7'
```

Then I run:
python-inspector --python-version 310 --operating-system linux --json-pdt /tmp/ort-PythonInspector8051204820648432355/python-inspector11825923102464191214.json --analyze-setup-py-insecurely --requirement /temp/requirements-from-pipenv.txt --verbose

Then I get the following stacktrace:

```
