Compiles nicely though…

I felt the #define WIFI_LoRa_32_V3 true in the pins_arduino.h was wrong so I deleted that line in C:\Users\<user>\.platformio\packages\framework-arduinoespressif32\variants\heltec_wifi_lora_32_V3\pins_arduino.h and added it via build_flags. No further mods to the core package files needed.
