Heltec ESP32 LoRa v3 Arduino library now supports Wireless Stick v3

My alternative Heltec Arduino library supports the “Heltec ESP32 LoRa v3” and now also the “Heltec Wireless Stick v3”. It’s well-documented and features a working LoRaWAN / TTN example that uses my EEPOM emulation in the ESP32’s RTC RAM instead of flash for most writes.
