Added ESP32 Support

This adds support for ESP32.

*** TESTS
Tested:
ESP32 Support fully tested in online mode (Tested with ESP32_DevkitC_V4):
- DNS: playstation.net redirected ok, playstation.com blocked ok
- HTTPS: works ok on PC (with of course certificate warning) and ok on PS5
- PS4 Tests: User Guide redirect works, Tested GoldHEN 2.3 on PS4
- PS5 Tests: User Guide Redirect Works, Tested SpecterDev's exploit on PS5

Untested:
- offline mode not tested
- ESP8266 not fully tested with these changes. It is supposed to have no impact on ESP8266.

**** ESP32 Compilation
For people who want to compile this:
- IP_NAPT errors: Some SDKs don't have NAT support enabled for ESP32 so I had to use an unofficial build of the ESP32 Library for Arduino. See:  espressif/arduino-esp32#6421 (comment)

- TAG ESP_LOGI errors: ESP32_HTTPS_SERVER seems to have some code incompatible with some SDKs, I had to manually edit one of the files, see:  fhessel/esp32_https_server#156 (comment)
