Pack the Nodes message more tightly #74
Description
Description
Currently ENRs for Nodes message are packed considering the max ENR size, i.e. max 4 ENRs per packet to fit the max packet size in the worst case.
If ENRs are smaller then more records could be packed into a single message.
Also need to consider that the message can be sent withing both OrdinaryMessage and Handshake packets. However for Nodes message (as a response message) this situation is highly unlikely to occur with a honest remote node, so probably just controlling and dropping outgoing too large message would be enough.
