Description of Change
Multi-switch plugs that support Electrical Sensor on multiple endpoints are not currently handled correctly in the driver, as the electrical handling is silently dropped when creating a profile for all child devices. This PR aims to fix that by adding handling of the PowerTopology cluster, a required cluster for the Electrical Sensor device type.
This cluster primarily indicates how Electrical Sensors are organized on the device through its feature map, and this PR handles 2 of the permutations, namely SET and NODE. For now, all other permutations (primarily TREE) will be silently dropped if it is supported, though we know of no real devices using this topology.
In the spec, a NODE topology indicates that there is only one source of electrical readings for the entire device, the "node". A SET topology indicates that the electrical sensor supports readings for some subset of the devices, and therefore there are likely >1 of these sensors, each with a SET topology and each supporting readings of different endpoints. These endpoints are specified through the AvailableEndpoints attribute, which we read on an initial join.
