[VOL-4069] Measure and read Rx optical power for an ONU
Reading Rx optical power requires triggering an RSSI measurement and tracking the RSSI Measurement Completed indication.
The raw value is converted to mW, and a dBm value is returned back.
A small test application (~40K) is bundled within the Debian package to help with debugging the optical power levels.
