This PR adds three cell-level kzg functions required for the sparse blobpool (eth/72). - VerifyCells: Verifies cells corresponding to proofs. This is used to verify cells received from eth/72 peers. - ComputeCells: Computes cells from blobs. This is needed because user submissions and eth/71 transaction deliveries contain blobs, while eth/72 peers expect cells. - RecoverBlobs: Recovers blobs from partial cells. This is needed to support both eth/71 and eth/72 --------- Co-authored-by: Felix Lange <fjl@twurst.com>
