/**
 * Query the network for block by id, height or get the latest block.
 *
 * Block ID is SHA3-256 hash of the entire block payload. This hash is stored as an ID field on any block response object (ie. response from `GetLatestBlock`).
 *
 * Block height expresses the height of the block on the chain. The latest block height increases by one for every valid block produced.
 *
 * @param queryOptions Query parameters
 * @param queryOptions.sealed Whether to query for a sealed block
 * @param queryOptions.height Block height to query
 * @param queryOptions.id Block ID to query
 * @param opts Optional parameters
 * @returns A promise that resolves to a Block object
 *
 * @example
 * import * as fcl from "@onflow/fcl";
 *
 * // Get latest block
 * const latestBlock = await fcl.block(); // Get the latest finalized block
 * const latestSealedBlock = await fcl.block({sealed: true}); // Get the latest sealed block
 *
 * // Get block by ID (uses builder function)
 * await fcl.send([fcl.getBlock(), fcl.atBlockId("23232323232")]).then(fcl.decode);
 *
 * // Get block at height (uses builder function)
 * await fcl.send([fcl.getBlock(), fcl.atBlockHeight(123)]).then(fcl.decode)
