Warn about duplicate responses

[AiyionPrime]

Is there an option to let yanic warn about unexpected multiresponses?

Consider a network where two nodes have the same nodeid (which should not, but sometimes does happen).

Yanic requests an answer from all nodes and receives an answer from each.
Usually yanic could expect answers in a 1:1 rate to its requests, or slightly below.

If there are two nodes sharing the same nodeid, yanic would receive answers in a ration 2:n for a given nodeid where n is the amount of nodes sharing this particular nodeid.

Every tool after yanic, like freifunk-maps can only see the latest answer, which yanic aggregated.

It would be worthwhile if yanic would warn about answers, where the ratio is of.

@genofire what do you think about this?

We have already an error-message if somebody try to use same nodeid but has interfaces:

yanic/runtime/nodes.go

Line 232 in de262a7

log.Warnf("override nodeID from %s to %s on MAC address %s", oldNodeID, nodeID, addr)

A calculation of duplicated response/ratio is hard to implement, because of the delay time of the nodes, so i do not like to develop it.
But yes it is possible ... it is just a strange error, because the nodeid should be generated by the hardware-address which should be unique.
