fix: gossipsub version and "iwant" parameter

[Wazzymandias]

Motivation

• Hubs experience spikes of duplicate messages
• Duplicate messages should not propagate to application layer if seen in p2p layer
• However, high message throughput can be I/O intensive and delay propagation. Delayed messages can reduce peer scores and yield negative feedback loop.

Change Summary

• Expose environment variable GOSSIPSUB_IWANT_FOLLOWUP_MS
• Pass in gossipsubIWantFollowupMs parameter in gossipNodeWorker
