Request to include datagram type for sockets

[Copperhead-Labs]

Is it possible to enhance the adafruit_esp32spi_socket.socket class to include datagram (UDP) socket type? This needed to allow connections with UDP only services like NTP.

I don't know if there are plans to add UDP socket support, but you mentioned NTP, so I thought I'd let you know the NINA firmware on the ESP32 does NTP and that time is available via this library's get_time() in case that is useful.

@cs0ckn Yep - but you will need to do some hacking to expose it. As mentioned by @docmollo, there's a NTP method in ESP32SPI which uses the ESP-IDF's NTP API directly (nice helper library here: https://github.com/adafruit/Adafruit_CircuitPython_NTP)

In adafruit_esp32spi, you can specify the conn_mode as UDP_MODE (https://github.com/adafruit/Adafruit_CircuitPython_ESP32SPI/blob/master/adafruit_esp32spi/adafruit_esp32spi.py#L616).

Feel free to submit a PR!

There was a PR to allow socket-level (datagram) UDP clients #127, example here https://github.com/adafruit/Adafruit_CircuitPython_ESP32SPI/blob/main/examples/esp32spi_udp_client.py.
