[Observium] Sensor limit nominal and delta OIDs need different scaling

Hi,

We are trying to set appropriate limits for a frequency sensor. There are OIDs for the nominal frequency and the acceptable deviation from it. The problem is the nominal OID needs 0.1 scaling while the deviation OID needs 1 scaling (the measured value needs 0.1 scaling). Is there a way to handle this? We tried using 'limit_scale' but that applies the same scaling to both the nominal and delta limits.

The specific device is a CyberPower ATS PDU. The OIDs are ePDU2SourceStatusSourceAFrequency, ePDU2SourceStatusSourceBFrequency, ePDU2SourceStatusNominalFrequency and ePDU2SourceConfigFrequencyDeviation.
