/**
 * Parse CSV to records.
 * This function is for parsing a binary stream.
 *
 * @category Middle-level API
 * @remarks
 * If you want to parse a string, use {@link parseStringStream}.
 * @param stream CSV string to parse
 * @param options Parsing options.
 * @returns Async iterable iterator of records.
 *
 * If you want array of records, use {@link parseBinaryStream.toArray} function.
 *
 * @example Parsing CSV binary
 *
 * ```ts
 * import { parseBinaryStream } from 'web-csv-toolbox';
 *
 * const csv = Uint8Array.from([
 *  // ...
 * ]);
 *
 * const stream = new ReadableStream({
 *   start(controller) {
 *     controller.enqueue(csv);
 *     controller.close();
 *   },
 * });
 *
 * for await (const record of parseBinaryStream(stream)) {
 *   console.log(record);
 * }
