Driving WS2812B LEDs using I2S on the Nordic nRF52832

Thanks Mahesh, even after three years I can also port it to the latest SDK with minor changes.

For those of you who might need some hints from this page later, the nrf_drv_i2s_start API has changed a little bit and the following modification will make it work again:

nrf_drv_i2s_buffers_t const initial_buffers = {
.p_tx_buffer = &m_buffer_tx[0],
};
err_code = nrf_drv_i2s_start(&initial_buffers, I2S_BUFFER_SIZE, 0);
APP_ERROR_CHECK(err_code);
