Signature:
create_cmd_area(
    shape_path: Union[str, pathlib.Path],
    column_name: str,
    output_path: Union[str, pathlib.Path],
) -> None
Docstring:
Apply iterative buffering to each feature and write polygon output.

This function reads the input dataset, computes a per-row buffer distance
so that each feature's buffered area approaches the value in the
``column_name``, replaces the geometry with the buffered
polygon, and writes the result to the
given ``output_path``.
Note: Use this function only when command area boundaries are not available, as the output
command areas from this function is an estimation, and may not be accurate. Hence, it should be used with caution.

Parameters
----------
shape_path : str or pathlib.Path
    Path to the irrigation canal network dataset readable by GeoPandas.
column_name : str
    Name of the column containing the target area for each feature. Should be in m2.
output_path : str or pathlib.Path
    Path to the output shapefile (including .shp extension) created by this function.

Returns
-------
pathlib.Path
    Path to the created command area shapefile.
