Currently, support for std::functional is gated by #if defined(ARDUINO_ARCH_ESP32) || defined(ESP8266)

This could be changed to #if __cplusplus >= 201103L to include other platforms that support <functional> such as Teensy.

Could also check the header guard for , such as _GLIBCXX_STD_FUNCTION_H for GCC, but then it gets compiler-dependent
