/**
 * For predeneb, SeenGossipBlockInput only tracks and caches block so that we don't need to download known block
 * roots. From deneb, it serves same purpose plus tracks and caches the live blobs and blocks on the network to
 * solve data availability for the blockInput. If no block has been seen yet for some already seen blobs, it
 * responds will null, but on the first block or the consequent blobs it responds with blobs promise till all blobs
 * become available.
 *
 * One can start processing block on blobs promise blockInput response and can await on the promise before
 * fully importing the block. The blobs promise is gets resolved as soon as all blobs corresponding to that
 * block are seen by SeenGossipBlockInput
