BugFix firmware downgrade to version with less settings: If a downgrade to a firmware version using less setting parameter were done then the settings had been reset to the default values. Root cause was that only increased number of settings was accepted by the read function. Because the layout of the setting structure is fixed (only bytes attached, no change in the order of data values) a downgrade just discarding the no longer used settings is possible => Updated read function to handle reduction of setting parameters.
