Complete project details at https://RandomNerdTutorials.com/esp32-cam-video-streaming-web-server-camera-home-assistant/
IMPORTANT!!!
- Select Board "AI Thinker ESP32-CAM"
- GPIO 0 must be connected to GND to upload a sketch
- After connecting GPIO 0 to GND, press the ESP32-CAM on-board RESET button to put your board in flashing mode

/* Modified by Francisco Vásquez
* - Configured to use SoftAP instead of connecting to a wi-fi network.
* - Added TCP server (PORT 50000) to core 0 for managing commands.
* - Reduced image resolution to increase framerate.
* - Removed other boards code and left only AI thinker for code simplicity.
