📄 Description

This very small patch enables a new feature to provide for an optional callback during the wifi config. It is optional, so non-disruptive to existing implementations. If setSetupLoopCallback is passed a function, that function will be called prior to yield() inside startConfigPortal. We use this to "fast flash" an LED to indicate (pin 2 on the NODEMCU) to indicate that the device is pending configuration, rather than in operational mode.
