PowNet v2.1 (Refactoring and Feature Release)

This release of PowNet introduces major refactoring for improved code organization and maintainability, along with several new features to enhance functionality and user experience.

**Key changes: **

• **Simplified Modeling Workflow: ** All modules have been refactored to streamline the modeling process and make the codebase easier to understand and extend. This includes:
  • Reduce the number of function calls required by a user
  • Streamlined solver selection
  • Simplified user inputs by switching from config files to direct arguments in functions and classes
• **Enhanced Modeling/Solver Capabilities: **
  • Enabled model updating at every simulation step instead of building an instance from scratch
  • Added rounding heuristics to improve the optimization problem-solving process
• **New Analysis Features: **
  • Fixed modeling in a rolling horizon fashion
  • Allowed aggregation of generators at a node
  • Added the stochastic module for generating synthetic time series
  • Added locational marginal price (LMP) calculation and plotting functionality
  • Separated shortfall and curtailment penalty factors for more granular control over penalties
• **Improved User Experience: **
  • Increased flexibility in selecting input and output folders. This allows users to install PowNet as a package and work within their own project directories
  • Added input checking to help users identify and correct potential errors in their input data

**Other improvements: **

• **Increased Code Reliability: ** Added unit tests to ensure code quality
• **Bug Fixes: ** Fixed the handling of line loss calculations.
• **Improved Codebase: ** Revised folder structure for better organization.
• **Enhanced Documentation: **
  • Revised CSV field descriptions for clarity
  • Added API documentation
• **Code Cleanup: ** Deleted unused files to reduce clutter.
