Pull Request Overview

This PR adds a comprehensive vector editing feature to MapLibreMap by introducing the add_vector_editor() method, which combines Geoman drawing controls with an interactive property editor widget.

Key Changes:

• Adds add_vector_editor() method that loads vector data (GeoJSON, shapefiles, URLs, or GeoDataFrames) and provides an interactive UI for editing feature geometries and properties
• Implements automatic property inference from data when properties aren't explicitly specified
• Adds geojson_bounds() utility function to calculate spatial bounds using shapely
• Modifies JavaScript to use delete/import approach for feature loading to ensure proper editability
