network ip_address doesnt work if using wifi_esp32s2

Just had fun tracking this down, the wifi object loaded can be wifi_coprocessor or wifi_esp32s2, the ip_address method assumes _wifi has an ".esp" object it can call "ip_address" on, but for the esp32s2 one, its ".radio"

Start in adafruit_matrixportal/network.py around line 90, where the network helper's ip_address method is described as assuming an .esp object. Compare the wifi_coprocessor and wifi_esp32s2 object shapes, then verify that ip_address works with both implementations.
