Changes: - allow serializing to / from pandas DataFrames containing `pygeos` geometries (see `README.md` for details). - use new CRS object in geopandas data frames (4) - BREAKING: dropped `to_shp`; use geopandas `to_file()` instead.
0.2.0
- allow reading a subset of columns from a feather file - store geometry in 'geometry' column instead of 'wkb' column (simplification to avoid renaming columns)
