- Move interpolation from DatabaseUtil - Add the logic to wrap processed history map to BatteryLevelData - Change ImmutableList to List in BatteryLevelData because ImmutableList.of doesn't support null element. Bug: 236101687 Test: make RunSettingsRoboTests Change-Id: I0a842f24e5481faf65f667c08a4fdc11fe2f235c
