Refactor utility scripts to handle move to requirements.txt from Pipfile

[txoof]

The project has moved from pipenv to use plain requirements.txt. There needs to be a utility script that can run across all of the .py files to locate and write the requirements files for each plugin and the main program.

• Write a utility script to locate and update requirements files
  • Locate all requirements out of base modules
  • Locate all requirements from plugin modules
