Improve EEPROM version parsing
Improve EEPROM version parsing

* This is a bugfix to avoid placing multiple periods in the version
  string.

* The version number retrieved from bot comes back in a format like
  '502' for 5.2. The string needs to be modified to be like '5.2' for
  reading the eeprom map files.

* This was done by replacing zeroes with dots

* Improved with slightly more robust string munging and added some
  logging messages so we can see future issues more easily
