Not adding all required packages that are used in the Django project

In my project along with Django package, I have installed other packages ie. **django-crispy-forms** and so on. However, when I use the pipreqs only the Django package is added but not other required packages.

Start by reproducing the report in a Django project that imports django-crispy-forms and compare pipreqs output with the packages actually used. Trace how pipreqs identifies imports and maps them to package names. Done means the generated requirements includes django-crispy-forms and other used packages without regressing existing behavior.
