This script will read the flash memory of RDV4 and print the stored passwords/keys.

It was meant to be used as a help tool after using the BogRun standalone mode before SPIFFS.

You should now use data_read_pwd_mem_spiffs instead after the updated BogRun standalone mode.

(Iceman) script adapted to read and print keys in the default dictionary flashmemory sections.
