Low-level latency setting support.

Sets the size of the DirectSound host buffer.
When flags contains the kWinDirectSoundUseLowLevelLatencyParameters this size will be used instead of interpreting the generic latency parameters to Pa_OpenStream(). If the flag is not set this value is ignored.

If the stream is a full duplex stream the implementation requires that the values of framesPerBuffer for input and output match (if both are specified).
