openEO Python client v0.12.0

Added

• Allow passing raw JSON string, JSON file path or URL to Connection.download(),
  Connection.execute() and Connection.create_job()
• Add support for reverse math operators on DataCube in apply mode (#323)
• Add DataCube.print_json() to simplify exporting process graphs in Jupyter or other interactive environments (#324)
• Raise DimensionAlreadyExistsException when trying to add_dimension() a dimension with existing name (Open-EO/openeo-geopyspark-driver#205)

Changed

• DataCube.execute_batch() now also guesses the output format from the filename,
  and allows using format argument next to the current out_format
  to align with the DataCube.download() method. (#240)
• Better client-side handling of merged band name metadata in DataCube.merge_cubes()

Removed

• Remove legacy DataCube.graph and DataCube.flatten() to prevent usage patterns that cause interoperability issues
