Currently the /range/sources endpoint is documented to return a list of objects with nodeId and sourceId values when multiple nodeIds are requested, however it only returns a list of sourcesIds.

As the behaviour of the existing endpoint can't be changed either a new endpoint that returns this format is needed or, a param needs to be added to the existing endpoint to change the response content.

The documentation will also need to be updated.

Expected output:

{
"success": true,
"data": [
{"nodeId":1, "sourceId":"Main"},
{"nodeId":2, "sourceId":"Main"},
{"nodeId":2, "sourceId":"Main1"}
]
}
