>>> max_rows = 5e0 # 25e4
>>> chunks_dict = split_dataframe(df0, max_rows)
>>>
>>> dir0 = "../../data/i0000-data-chunks/"
>>> dir0 = pathlib.Path(dir0)
>>> dir0.mkdir(mode=0o700, parents=True, exist_ok=True)
>>>
>>> for key, chunk in chunks_dict.items():
>>>     print(f"{key}: {chunk.shape}")
>>>     # print(chunk)
