Icon LinkPredicate ID

For an input of type InputType.Coin or InputType.Message, input, the predicate owner is calculated as: sha256(0x4655454C ++ CHAIN_ID ++ root(input.predicate)), where root is the Merkle root of the binary Merkle tree each leaf being 16KiB of instructions. If the bytecode is not a multiple of 16 KiB, the final leaf should be zero-padded rounding up to the nearest multiple of 8 bytes.
