    """
    Reverse JCQ demand and control answers.

    This function recodes answers in Job content questionnaire
        by first incrementing them by 1, to be in line with original (1-4) scoring.
    Then, some answers are reversed (i.e. 1 becomes 4 etc.),
        because the questions are negatively phrased.
    These answers are listed in DICT_JCQ_DEMAND_CONTROL_REVERSE
        and identified by their question ID.
    However, the existing data is checked against literal phrasing of these questions
        to protect against wrong numbering of questions (differing question IDs).

    Parameters
    ----------
    df_esm_jcq_demand_control: pd.DataFrame
        A cleaned up dataframe, which must also include esm_user_answer_numeric.

    Returns
    -------
    df_esm_jcq_demand_control: pd.DataFrame
        The same dataframe with a column esm_user_score
            containing answers recoded and reversed.
