Store all relays bids

[ababino]

📝 Summary

Added the --with-duplicates flag to store duplicate bids from different relays. It changes the deduplication key to

fmt.Sprintf("%d-%s-%s-%s-%s-%s", bid.Slot, bid.BlockHash, bid.ParentHash, bid.Relay, bid.BuilderPubkey, bid.Value)

⛱ Motivation and Context

This will allow measuring builder to relay latencies
