ESP32 Camera Bot

#ESP32 Camera Bot
## Motivation
I searched for a nice vehicle to test the ESP32 camera bot source code. The code is based on the nice project by Mudassar Tamboli and bitluni. See here for details: [Websocket Video Camera](https://medium.com/@mudassar.tamboli/esp32-ov7670-websocket-video-camera-26c35aedcc64
). I had to modify the code a bit to add an I2C display which did not work with the I2C bitbanging code of Mudassar Tamboli.
I liked the Drogerdy 2.0 because it uses the standard geared motors which I had lying around. By Using a DRV8833 motor driver I could live with a standard power bank for a supply. I thought it would be a nice idea to use a power supply with built-in solar cells for a green touch...
