    >>> import dtoolkit.geoaccessor

    Points to h3 indexes.

    >>> s = pd.Series(
    ...     [
    ...         "POINT (122 55)",
    ...         "POINT (100 1)",
    ...     ],
    ... ).from_wkt(crs=4326, drop=True)
    >>> s
    0    POINT (122.00000 55.00000)
    1     POINT (100.00000 1.00000)
    dtype: geometry
    >>> s.to_h3(8)

Advices for h3-pandas

1. use import h3.api.numpy_int as h3 instead of import h3
2. compat with h3-py 4
3. requires crs is 4326
4. consider h3-py as the accessor of Series
5. Speed up creating points / polygons via shapely 2.x
