Refactored for the ESP-32

Proof of concept is here:

If you are using one of the Heltec ESP32 that come with Oled mini display:

Way faster than ESP8266

Uploading the JPG takes now about 3 / 4 seconds depending on your selected resolution. That is between 20 to 30% increase compared to previous version.

No more SPIFFS

Since SPI Flash File system is slow and not really designed to store 200Kb images on the fly we will keep the save to saveInSpiffs Flag disabled as default in this sketches.

No more compiled binaries on ESP32

Since it's an ongoing project, no more bynaries will be provided for ESP32 related branches.
