add vulnerable nodes

[willcl-ark]

Few easy vulns, based on bitcoin core v28rc2

To use add the custom version string into version of the graph.

cc @m3dwards, in case you fancy playing around with some easier scenarios :)

Yep happy to

[pinheadmz]

concept ACK
Didn't review code but with this patch i can deploy a cluster with all 12 supported versions (x10 = 120 tanks!)

A few of these vulns are way too easy to exploit and they end up crashing right after the network starts up!

99.1.0-unknown-message

There are old nodes on this network still sending "reject" packets, which were removed and therefore unknown in newer nodes.

Couldn't tell exactly what happened to this one but some tx from the tx_flood scenario knocked it over. I'll try to dig up the evil tx for analysis

This one took a while with tx_flood so it might be ok, just very very fragile

Ok I have attempted to mitigate this by only counting unknown p2p messages from nodes who are using protocol version 70016 (new nodes).

I don't understand how this could hit from tx_flood, so logs would be ideal here.

Mitigated (slightly) be requiring 5k invs counted per node now, which should slow things down a bit? Perhaps I should also bump the numbers though too...
