/**
 * A job that convert a PDF file into a searchable PDF file. Allows specifying locale({@link OCRSupportedLocale}) and

 * @example
 * Sample Usage:
 * ```js
 *         const readStream = fs.createReadStream("<SOURCE_PATH>");
 *
 *         const credentials = new ServicePrincipalCredentials({
 *             clientId: process.env.PDF_SERVICES_CLIENT_ID,
 *             clientSecret: process.env.PDF_SERVICES_CLIENT_SECRET
 *         });
 *
 *         const pdfServices = new PDFServices({credentials});
 *
 *         const inputAsset = await pdfServices.upload({
 *             readStream,
 *             mimeType: MimeType.PDF
 *         });
 *
 *         const job = new OCRJob({inputAsset});
 *
 *         const pollingURL = await pdfServices.submit({job});

 *
 *         const resultAsset = pdfServicesResponse.result.asset;
 *         const streamAsset = await pdfServices.getContent({asset: resultAsset});
