[feature] timeseries: Enable saving of compressed CSV files

[jokabrink]

When setting up the OutputWriter() object, passing output_file_type=".csv.zip" should not result in a warning or error, but instead tell Pandas to save the data using the inferred compression format. This is possible because the documentation in https://pandas.pydata.org/docs/reference/api/pandas.DataFrame.to_csv.html allows for inferred compression types from file name.

Thank you @jokabrink this is a nice feature!

Please add a minimal test for this feature in pandapower/test/timeseries/test_output_writer.py and mention the change in the CHANGELOG file.
