- Pass on nett argument to query_generation_per_plant - Refactor and generalize _calc_nett_and_drop_reduntant_columns to cope with 3 column levels (unit/psr_type/aggregation) - Warning: this removes df.squeeze() at the end of the netting. df.squeeze() gives inconsistent results according to the number of columns in a dataframe (structure is different if by coincidence only one technology or plant unit is present in the data).

Warning: I removed the df.squeeze() at the end of the netting, because it's an unsafe operation on dataframes:
df.squeeze() gives inconsistent results according to the number of columns in a dataframe. The structure of the columns becomes different if (by coincidence) only a single psr_type (in case of aggregated generation) or a single plant unit (in case of unit generation) is present in the queried data.
A specific column level can be removed with the following operation (=safer than squeeze):
df = df.droplevel(1, level_index)
(removing level_index of the multiindex column axis).
