    Chooses heat demand profiles for each residential and CTS building

    This dataset creates heat demand profiles in an hourly resoultion.
    Time series for CTS buildings are created using the SLP-gas method implemented
    in the demandregio disagregator with the function :py:func:`export_etrago_cts_heat_profiles`
    and stored in the database.
    Time series for residential buildings are created based on a variety of synthetical created
    individual demand profiles that are part of :py:class:`DataBundle <egon.data.datasets.data_bundle.DataBundle>`.
    This method is desribed within the functions and in this publication:
