Persist RTC value across resets #78
Description
The RTC values seems to be getting reset to the default value on a system reset, but should persist if battery backup is present. This issue appears to be with FeatherLib, requiring an update there. A fix should be scheduled into the next FeatherLib release/test cycle.
