std::pair<int64_t, int64_t> NumPacketsAndFramesPerBatch (AudioRendererShim<SampleType> * renderer)

All pipeline tests send batches of packets. This method returns the suggested size for

each batch. We want each batch to be large enough such that the output driver needs to

wake multiple times to mix the batch -- this ensures we're testing the timing paths in

the driver. We don't have direct access to the driver's timers, however, we know that

the driver must wake up at least once every MinLeadTime. Therefore, we return enough

packets to exceed one MinLeadTime.
