pysteps v1.3.1

Summary of main changes and new features:

• Add an interface to the feature.blob_* methods from scikit-image. A blob is defined as a local maximum of a Gaussian-filtered image. This new utils.images.blob_detection feature detection method can be used in the motion.lucaskanade module to track cells in radar data.
• Fix installation errors in windows which caused permissions errors in datasets.download_pysteps_data and datasets.download_mrms_data functions.
• Fix bug with the precipitation mask of nowcasts.anvil. This caused the method to produce too much rain in non-rainy areas when rain rate was used as input.
• Run Black on the whole source code for consistent, reproducible code formatting.
• Add pre-commit hooks as part of the development workflow.
• Improve documentation.
