i2s_stream does not zero DMA buffer in 32 bits mode (AUD-600)

2

When I stop playing a 32 bit sample I get a lot of noise. This is due to not zeroing the DMA buffer completely. In ```i2s_stream.c``` function ```_i2s_close(audio_element_handle_t self)```: ```...

Make sure DMA buffer is zeroed in 32 bits mode. (AUD-594)

DMA buffers for I2S must be set to zero to prevent noise after playback stops. This works well in 16 bits mode. In 32 bits mode leaves some samples in...

Add quick start example with plot

The quick start section should show a few common usecases, and be clear in terms of usage patterns.
