What does this PR do? Why is it needed?
Our current packing algorithm for Electra is very non-optimal and was only supposed to be used in devnets, where the network is very small and communication between nodes is very reliable, resulting in a small number of aggregates. This algorithm creates only one on-chain attestation per an
attestation_data+committee
combination. It means that if there are two aggregates for the same data and committee, the one with less attestation bits will always be dropped, even if it could be packed into a block.The new algorithm loops through aggregates until all of them are included in an on-chain attestation.
