v2.0-beta

With this release the increasing difficulties to set up a valid conda environment should be addressed. It is expected that this release has issues and hoped that they can be identified and addressed soon.

changed environment:

• geopandas version up to 0.8 compatible
• conda-forge is first choice channel now, because there were several issues with the default channel

major changes:

• climada.entity.exposures.Exposures restructured, unshackled from GeoDataFrame inheritance, uses composition instead.
• The GeoDataFrame data is now a property of the Exposures object: exposure.gdf.
• The default crs, climada.util.constants.DEF_CRS is now 'EPSG:4326'. It used to be {'init': 'EPSG:4326'}.
• The changed default format is now correctly interpreted by the CRS.from_user_input method of both packages, rasterio and pyproj.
• The crs format {'init': '[source]:[id]'} is not generally accepted anymore. In certain cases the crs have to be redefined to be compatible with climada 2.x.
