Add EEPROM debug printouts, error check to example (#6556)

Browse Source 
* Add EEPROM debug printouts, error check to example

Add debug printouts when EEPROM calls fail, even if the API doesn't
allow returning a success/failure code.

Adds error checking to the example to make it explicit that when you
call EEPROM::commit(), you need to look at the result code in your code.

Fixes #6551 , or would fix it if there was error checking in the MCVE.

* Clarify example error message
