Option for esp32 formatting replacing unsigned char and PROGMEM with just "uint8_t"

[Gaai]

The PROGMEM is very usefull for arduino boards. But not for esp32. It would be nice if we had an option for esp32 formatting. Replacing const unsigned char with const uint8_t and removing the PROGMEM keyword alltogether.

Thanks for this tool btw! It is already very usefull the way it is. Saving us a lot of efford.
