default_turbine_data missing in installer

[maurerle]

The default_turbine_data is missing in the installer. Also: I get an error when downloading the latest wind turbine data:

>>> from windpowerlib.data import store_turbine_data_from_oedb, fetch_turbine_data_from_oedb
>>> df = store_turbine_data_from_oedb()
