/**
* Renders a PDF417 barcode matrix to a canvas and returns it as a data URL.
*
* This function creates an HTML canvas element, draws the barcode by iterating through
* the barcode matrix, and converts the canvas to a base64-encoded PNG data URL that
* can be used as an image source.
*
* @param barcodeMatrix - The barcode array generated by the PDF417 encoder containing
* the barcode matrix data with dimensions and binary code values
* @param blockWidth - The width in pixels of each individual barcode module (bar/space unit)
* @param blockHeight - The height in pixels of each individual barcode module (bar/space unit)
*
* @returns A data URL string (base64-encoded PNG) representing the rendered barcode image,
* suitable for use in an HTML img src attribute
*
* @example
* ```typescript
* const pdf417 = createPDF417();
* pdf417.init("Hello World", 2, 2);
* const barcodeArray = pdf417.getBarcodeArray();
* const dataUrl = renderBarcode(barcodeArray, 2, 4);
* // dataUrl can now be used: <img src={dataUrl} />
* ```
