import leafmap.foliumap as leafmap is unable to add_gdf if style column is present

Description

Trying to use add_gdf function fails with foliumap version of leafmap if the gdf has style column. The same functionality works with import leafmap.leafmap as leafmap.

show_what_works = False

if show_what_works:
    import leafmap.leafmap as leafmap
else:
    import leafmap.foliumap as leafmap
import geopandas as gpd
from shapely.geometry import Polygon

dict_with_style = {"name": ["A", "B", "C"], "geometry": [Polygon([(77.0, 28.0), (77.0, 29.0), (78.0, 29.0)]), Polygon([(77.0, 29.0), (77.0, 30.0), (78.0, 30.0)]), Polygon([(77.0, 30.0), (77.0, 31.0), (78.0, 31.0)])], "style": [{"color": "red"}, {"color": "green"}, {"color": "blue"}]}

gdf_with_style = gpd.GeoDataFrame.from_dict(dict_with_style, crs="EPSG:4326")
print(gdf_with_style)

m = leafmap.Map()
m.add_gdf(gdf_with_style, zoom_to_layer=True)
m

Prof. @giswqs, I found a small problem with this. Not sure if it's worth opening a new issue so raising it here. When GeoPandas loads a GeoJSON with "style", by default, all "style" elements are in str format. This works fine with import leafmap.foliumap as leafmap but fails with import leafmap.leafmap as leafmap. Here is the MWE:

show_what_fails = True

if show_what_fails:
    import leafmap.leafmap as leafmap
else:
    import leafmap.foliumap as leafmap

collection = {
  "type": "FeatureCollection",
  "features": [
    {
      "type": "Feature",
      "geometry": {
        "type": "Polygon",
        "coordinates": [
          [
            [80.778174, 26.654166],
            [80.778882, 26.65477],
            [80.778657, 26.654981],
            [80.777949, 26.654377],
            [80.778174, 26.654166]
          ]
        ]
      },
      "properties": {
        "name": "Example",
        "style": {
          "color": "red",
        },
      }
    }]
}
gdf = gpd.GeoDataFrame.from_features(collection)
print(type(gdf.iloc[0].style))  # This is a dict
gdf.to_file("/tmp/tmp.geojson", driver="GeoJSON")
gdf = gpd.read_file("/tmp/tmp.geojson")
print(type(gdf.iloc[0].style))  # This is a str

m = leafmap.Map()
m.add_gdf(gdf)
m

You can open a new issue. I will look into it.
