We should be able to put maps and deal with them properly within a ZIM files

Maps/GIS have a large number of options with varying degrees of complexity. Here's a pretty good non-exhuastive-but-huge list for reference:

To narrow down options, we should outline more specific requirements for how we want to handle maps.

Considerations (off the top of my head, non-exhaustive):

• Embedded data type
  • Vector (svg, shapefile) vs. Raster (png, jpg, avif, jxl, webp, some other raster tile format)
  • single type vs multiple supported types
  • lossless vs lossy
• Library license compatibility
• Dependency stack
• Whether or not we want to support layering
