      Decorator implementation that wraps a check around an ESPLoader
      bootloader function to check if it's supported.
  
      This is used to capture the multidimensional differences in
      functionality between the ESP8266 & ESP32 ROM loaders, and the
      software stub that runs on both. Not possible to do this cleanly
      via inheritance alone.
