0.9.1

• Upgraded to Spark 2.4.7
• Added pyspark.sql.DataFrame.display(num_rows:int, truncate:bool) extension method when rf_ipython is imported.
• Added users' manual section on IPython display enhancements.
• Added method_name parameter to the rf_resample method.
  • BREAKING: In SQL, the function rf_resample now takes 3 arguments. You can use rf_resample_nearest with two arguments or refactor to rf_resample(t, v, "nearest").
• Added resample method parameter to SQL and Python APIs.
• Upgraded many of the pyrasterframes dependencies, including:
  descartes, fiona, folium, geopandas, matplotlib, numpy, pandas, rasterio, shapely
• Changed rasterframes.prefer-gdal configuration parameter to default to False, as JVM GeoTIFF performs just as well for COGs as the GDAL one.
• Fixed #545.
