lavfi/avf_showspatial: add framerate option 

Apparently this option was intended (the context contains a
currently-unused frame_rate field), but was never added. This results in
the output timebase being unset after config_output(), so the input
audio timebase ends up being used for video output, which is clearly
wrong.

Add an option for setting output video framerate. Also set output frame
durations.
