 * A job that combines multiple PDF files into a single PDF file. Allows specifying which pages of the source files

 * Sample Usage:
 * ```js
 *         const readStream1 = fs.createReadStream("<SOURCE_PATH>");
 *         const readStream2 = fs.createReadStream("<SOURCE_PATH>");
 *
 *         const credentials = new ServicePrincipalCredentials({
