LED_BUILTIN is NOT defined for all ESP32 boards - some do not have a built-in LED! Instead, Status LED now defaults to Pin 13, as opposed to LED_BUILTIN. Also, added a new method, homeSpan.getStatusPin(), to return the pin number used for the Status LED, whether or not it remains the default (13) or is changed by user with homeSpan.setStatusPin(pin). This method is now used in the DEV_Identify.h file for each example, instead of using LED_BUILTIN (which otherwise won't compile for boards without a built-in LED)
Zephyr3, the latest version, was moved into its own repo and renamed ZephyrVentHood.
Deleted Zephyr1, Zephyr2, and Zephyr3, which are no longer needed.
Flattened folder structure for Examples and placed them all in top-level directory
