[BUG] index.d.ts: stream.xlsx.WorksheetReader declares no name, though WorkbookReader assigns one

Description

lib/stream/xlsx/workbook-reader.js assigns each WorksheetReader its name from the workbook's sheet index, and it is the natural way to identify a worksheet yielded by for await (const worksheet of reader). But index.d.ts declares no name on the class, so TypeScript consumers have to cast to reach it.

Suggested fix

class WorksheetReader {
constructor(options: WorksheetReaderOptions);
+   name: string;
read(): Promise<void>;
