python3-brotlicffi (Python CFFI bindings to the Brotli library)

This library contains Python CFFI bindings for the reference Brotli
encoder/decoder. This allows Python software to use the Brotli
compression algorithm directly from Python code.

NOTE: build will FTB if you've installed python3-cffi and then
      removed it without reinstalling 15.0's python-ciffi.
