This commit introduces a new script, cleanup_worldmap.py, which provides a utility for cleaning and normalizing the SVG file worldmap.svg. The script performs various transformations including:
- Normalizing path tags and attributes
- Adding data-iso attributes based on a provided JSON mapping
- Pretty-printing the SVG output
- Creating a backup before overwriting the original file when using the --in-place option
The script is designed for ease of use with command-line arguments and includes error handling for XML validation.
