Subject: [PATCH] Store only changed parameters in flash instead of all
 Rationale: 1. Parameters NVS storage is limited and storing unchanged
 parameters is wasteful. 2. This allows changing parameters in the code
 without having to erase the flash storage. 3. Updating the firmware version
 may change the parameter defaults.
