Example using adafruit_connection_manager

Example using adafruit_connection_manager to allow alternate radios (sources of sockets)

Addresses:
adafruit/Adafruit_CircuitPython_Wiznet5k#132

Tested with CP9.0.0.* on:
Adafruit QY Py ESP32-S3
Raspberry Pi Pico W
Adafruit Ethernet FeatherWing

Tested on Adafruit PyPortal, but ESP32SPI currently has no context manager for sockets, and the NTP library requires this.
