Lack of ESP32 platform support

[klosso]

I have worked with clock based on esp32 board with this very good lib, but there is lack of support for EEPROM for writing and reading.
I have locally added support but, don't know haw to push this with review.

here is pure diff if You are interest :

any chance I could get a link to the files that you have changed or a better paste of the code changes / additions

Me too! Or maybe we can help you get this into a pull request, @klosso
