ScenarioList Source Refactoring Checklist

This document outlines the refactoring process to move the from_X methods from ScenarioList to child classes of Source.

Refactoring Process

For each source type, follow these steps:

1. Create a new child class of Source in scenario_source.py
2. Add a deprecated classmethod in ScenarioList that references the new source class
3. Run pytest to confirm everything works correctly
4. Move to the next source type
