Pull Request Overview

This PR updates argument consistency throughout the halfmoon package to match the .exposure parameter name from propensity scoring functions. The changes standardize parameter naming to improve consistency and user experience across the API.

Key changes include:

• Renamed treatment to .exposure and weights to .weights throughout test files
• Updated .wts to .weights in function calls
• Changed reference_group to .reference_level for categorical variables
• Updated treatment_level to .focal_level for focal level specifications
