2.1.8
Fix an unhandled OSError when FFmpeg is not installed.

2.1.7
Properly close some filehandles in the FFmpeg backend. The maddec backend now \ 
always produces bytes objects, like the other backends. Resolve an audio data \ 
memory leak in the GStreamer backend. You can now optionally specify which \ 
specific backends audio_open should try. On Windows, avoid opening a console \ 
window to run FFmpeg.
