Added a HAL module for the I2S peripheral
Audio (Morse code) demo for I2S in "controller mode" (formerly referred to as "I2S master"),
transmitting audio signals to a DAC:
https://github.com/kalkyl/nrf-hal/blob/i2s/examples/i2s-controller-demo/src/main.rs
Tested on nRF52840-DK with a UDA1334a DAC
...or connect it to the...
"Peripheral mode" (formerly referred to as "I2S slave") demo,
using an RGB LED (APA102) to display the RMS level of the received I2S audio signal:
https://github.com/kalkyl/nrf-hal/blob/i2s/examples/i2s-peripheral-demo/src/main.rs
Tested on ItsyBitsy nRF52840 with its onboard RGB LED
