0.13.0 🌈

🚀 Features

• Transitioning from AnnData to EHRData
  EHRData replaces AnnData as ehrapy's core data structure to better support time-series electronic health record data.
  The key enhancement is native support for 3D tensors (observations × variables × timesteps) alongside the existing 2D matrices, enabling efficient storage of longitudinal patient data.
  A new .tem DataFrame provides time-point annotations, complementing the existing .obs and .var annotations for comprehensive temporal data description.
  While EHRData maintains full backward compatibility with AnnData's API, users can now seamlessly work with time-series data and leverage specialized methods for temporal analysis.
  Existing code using AnnData objects will continue to work, but migration to EHRData is strongly recommended to access enhanced time-series functionality.
