Crunchy aggregator (and p2p-viz) yields incorrect node results

[autotunafish]

I believe the issue (though it's basically a hunch) is that the crawler is incorrectly labeling node types as unknown (I think). When outputing the data with the following call "curl --data-binary '{"jsonrpc": "2.0", "id":0, "method": "getmetrics", "params": [] }' -H 'content-type: application/json' http://127.0.0.1:54321/ > crunchy/testdata/latest.json", and subsequently given to crunchy with the Zcash filter, it only returns the count of the protocol version "170018", of which there seems to be 16. I make this assumption based only on that number because thats the exact Zcash node count displayed in p2p-viz. I suppose the issue could be in crunchy but not sure. I couldn't really find where it compares protocol version to derive node type, this is what I suspect the issue to be.
