Backward compatibility of examples with ESP32 in Arduino 2.X IDE

[FranticPlus]

I managed to build and upload some of the examples/web files to an ESP32-Devkit-1 by reverting to older versions of the IDE/boards/libraries as indicated below.

1. SPIFFS uploader is no longer supported on Arduino 2.X so I installed Arduino 1..X and used the Java SPIFFS uploader to create the filesystem and upload the web server files for the Keybus Interface Web sketch. It would be nice (in future) if someone changed the SPIFFS format in these examples to Little FS.
2. I had to revert to v2.0.17 for the ESP32 board.
3. I had to revert to v6.19.3 of teh ArduinoJson libraries.
   The code works as indicated and I tested it on a DSC PC5005 panel (South African version).
   I just want to say thanks to taligent for the effort in decoding these protocols.
