/* Use this macro to store constant values in IROM flash instead
   of having them loaded into rodata (which resides in DRAM)

   Unlike the ESP8266 SDK you don't need an attribute like this for
   standard functions. They're stored in flash by default. But
   variables need them.

   Important to note: IROM flash can only be accessed via 32-bit word
   aligned reads. It's up to the user of this attribute to ensure this.
