docs: Overlays ``feature`` on the map. Returns a new Map.
  
          Args:
              ``feature``: a ``Table`` of map features, a list of map features,
                  a Map, a Region, or a circle marker map table. The features will
                  be overlayed on the Map with specified ``color``.
  
              ``color`` (``str``): Color of feature. Defaults to 'Blue'
  
              ``opacity`` (``float``): Opacity of overlain feature. Defaults to
                  0.6.
  
          Returns:
              A new ``Map`` with the overlain ``feature``.
