This commit updates the scaling of the link margin and RSSI metrics. The metric values are scaled when appended in the message (in a Report sub-TLV) or when they are read back from received message. The stored value in `MetricsValues` are changed to be always the actual metric value (not the scaled value). This ensures that the value are stored in proper int type (e.g., RSSI is `int8` vs the scaled value which is `[0,255]`). Methods are added to perform the scaling which now rounds to closest integer ensuring the reverse scaling gives back the original value. Unit test is added to validate the scaling methods.
