IDEA: add Bluetooth support for interactive gaming (Pong, Snake..)

[c64emulator]

There are already some plugins/modes (Break Out, Pong, Snake), where the ESP32 is playing with itself. That's boring...

IDEA: The ESP32 provides Bluetooth support (well, some like the S3 or C3 only BLE). This could be used for interacting on games. Using a Smartphone-App together with a Bluetooth-Lib for the ESP32, the games could go interactive!

• A more basic example of Bluetooth usage can be found at STEMpedia:
  Providing a Smartphone-App "Arduino ESP Bluetooth - Dabble" together with a Lib for the ESP32:

  • tutorial at <https://ai.thestempedia.com/docs/dabble-app/gamepad-module/>
  • example at <https://github.com/STEMpedia/DabbleESP32/blob/master/examples/03.Gamepad/03.Gamepad.ino>
  • lib at <https://github.com/STEMpedia/DabbleESP32>

• A working example for playing interactive games on a LED-Panel using Bluetooth provides Scott Marley:
  Note: The App for the Smartphone can be DIY-generated with the MIT APP Inventor <https://appinventor.mit.edu>
