Emulates Lodestar attestation packing algorithm to guess if a block was produced by Lodestar or not

https://github.com/ChainSafe/lodestar/blob/1b40a919e3c5fc882588a1d0fd0c3adf755dc939/packages/beacon-node/src/chain/opPools/aggregatedAttestationPool.ts#L169

Summarized in rules:

• Define validator as already having participated as having the flag isTimelySouce == true
• Participation is computed from the state.participation at the attestation’s epoch
• There is at max two attestations in a block with the same data root
• Define score as score = not_seen_attesters / (state.slot - slot)
• Attestations are perfectly sorted in descending score order
