This can reduce audio latency according to https://developer.android.com/ndk/guides/audio/opensl/opensl-prog-notes#perform. Previously we were using the hardcoded values of 48000 Hz and 256 frames per buffer. The sample rate we use with this change is 48000 Hz on all devices I'm aware of, but the buffer size does vary across devices. Terminology note: The old code used the term "sample" to refer to what Android refers to as a "frame". "Frame" is a clearer term to use for this, so I've changed OpenSLESStream's terminology. One frame consists of one sample per channel.
