Pull Request Overview

This PR represents a massive development effort that consolidates PyPLECS method interfaces, implements missing functionality, and establishes a comprehensive testing infrastructure. The changes unify variable loading methods, add extensive error handling, implement previously stubbed methods, and create a robust validation framework.

Key changes include:

• Unified load_model_vars() method supporting multiple input types (dict, .mat files, .yaml files)
• Complete implementation of missing methods in GenericConverterPlecsMdl class
• Comprehensive test suite covering unit, integration, and end-to-end workflows
• Shared utilities module for code reusability and testability

The method _parse_plecs_file_variables has no implementation beyond a comment and pass statement. This will cause issues when load_modelvars_struct_from_plecs calls it.
