This commit adds I2S protocol support for the esp32 and stm32 ports, via a new machine.I2S class. It builds on the stm32 work of blmorris, #1361. Features include: - a consistent I2S API across the esp32 and stm32 ports - I2S configurations supported: - master transmit and master receive - 16-bit and 32-bit sample sizes - mono and stereo formats - sampling frequency - 3 modes of operation: - blocking - non-blocking with callback - uasyncio - internal ring buffer size can be tuned - documentation for Pyboards and esp32-based boards - tested on the following development boards: - Pyboard D SF2W - Pyboard V1.1 - ESP32 with SPIRAM - ESP32 Signed-off-by: Mike Teachman <mike.teachman@gmail.com>
