squashed: - add SDIO pin aliases - add AnalogIO, touchIO, and USB pins. - change to GRB neopixel - add official USB PID (confirmed in espressif/usb-pids#344) - add normal SPI alias alongside wiznet5k

Not sure why CI failed only for zephyr here. AI suggests a protobuf version pinning mismatch. Is this due to the pull being against stable vs main? |

I suspect this is an issue on the 10.2.x branch. Please make a new PR against main. 10.3 should be out soon. |

Adding board definitions for a Waveshare ESP32-S3 based relay board:
product page: https://www.waveshare.com/esp32-s3-eth-8di-8ro.htm?sku=30838
I've tested all included i2c devices (RTC, GPIO Expander), the buzzer, RGB led, SPI Ethernet adapter and UART-RS485 converter, and isolated digital inputs via a CircuitPython script. Because the S3 has abundant memory, I've frozen relevant sensor and networking libraries.
Aside: My hope is to add more boards with industrial / ruggedized features. I've been conducting workshops for small/medium sized farm automation in Arduino. I feel that CircuitPython may be a better match for folks new to programming hoping to build moderately complex control logic.
One shortcoming is the lack of a frozen ModBus RTU library. Sensors using this protocol over RS485 are common in industrial controls/ HVAC. I note that existing libraries are large and contain GPL licensed code. Is it possible to freeze this library in a board's build: TwinDimension-CircuitPython-Modbus, or would it be of value for me to start work on a minimal, MIT licensed Modbus RTU library?
