v0.1.0

This is the initial release of imputify. In summary, it provides multiple imputation strategies for tabular datasets (KNN, Statistical, DAE, VAE, GAIN, and a fine-tuned decoder-only LLM), comprehensive evaluation metrics (reconstruction, distribution, and predictive), and missing data generation with MCAR, MAR, and MNAR mechanisms. All imputers follow scikit-learn's fit/transform API.
