Add Rachio Irrigation API Example

[DJDevon3]

Example pulls data from your Rachio Irrigation Timer. This is just a basic example. More can be done with zone scheduling, actually running the irrigation system, etc.. will work on an advanced example in the future. This should be good enough for very basic communication with the API and timer.

Because this API pulls very sensitive data I've included an asterix obfuscation for serial prints when not in debug mode. Debug mode will show all data without obfuscation. The below serial output is verbose, the asterix are intentionally part of the script.

Example serial output:

This looks good to me. Thanks for the new example @DJDevon3

I tested it successfully on a Feather ESP32S3 TFT.
