lecture 2020

• storm_europe: new module
  Provides models to calculate economic damages of European winter windstorms/extratropical cyclones.
• util.finance.gdp: new feature
  GDP data for the country TWN (Republic of China / Taiwan) is not provided by World Bank API usually called in climada.util.finance.gdp.
  As a workaround, a new feature is provided to call util.finance.gdp(’TWN’) returning GDP data from another data source (International Monetary Fund, IMF).
  The IMF data is not accessed via an API but from a static CSV-file available in the repository at data.system.GDP_TWN_IMF_WEO_data.csv.
  The file contains current GDP data from 1980 to 2024 (GDP data are estimates/ projections after 2018).
