Won't work with Ethernet as the Network Interface

[ianburton20]

Searches suggest that the library is built primarily for ESP-IDF's MQTT client encapsulation, which is agnostic to the network interface—whether it's Wi-Fi or Ethernet. So the library should be able to work with Ethernet-based communication on an ESP32 using the W5500 Ethernet controller and the ETH.h library. However as soon as you execute mqttClient.loopStart(); the ESP32 panics and core dumps.
