network ip_address doesnt work if using wifi_esp32s2

[castaway]

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"

return self._wifi.esp.pretty_ip(self._wifi.esp.ip_address)
