// v2 Usermod to automatically save settings
// to preset number AUTOSAVE_PRESET_NUM after a change to any of
//
// * brightness
// * effect speed
// * effect intensity
// * mode (effect)
// * palette
//
// but it will wait for AUTOSAVE_SETTLE_MS milliseconds, a "settle"
// period in case there are other changes (any change will
// extend the "settle" window).
//
// It will additionally load preset AUTOSAVE_PRESET_NUM at startup.
// during the first `loop()`. Reasoning below.
//
// AutoSaveUsermod is standalone, but if FourLineDisplayUsermod
// is installed, it will notify the user of the saved changes.
//
// Note: I don't love that WLED doesn't respect the brightness
// of the preset being auto loaded, so the AutoSaveUsermod
// will set the AUTOSAVE_PRESET_NUM preset in the first loop,
// so brightness IS honored. This means WLED will effectively
// ignore Default brightness and Apply N preset at boot when
// the AutoSaveUsermod is installed.
//How long to wait after settings change to auto-save

* CAUTION: serializeConfig() will initiate a filesystem write operation.
* It might cause the LEDs to stutter and will cause flash wear if called too often.
* Use it sparingly and always in the loop, never in network callbacks!
*
* addToConfig() will also not yet add your setting to one of the settings pages automatically.
