PDF generation with nodejs > 16 fails with RangeError

Server-side pdf generation with nodejs version > 16 fails with the following error:

RangeError [ERR_OUT_OF_RANGE]: The value of "size" is out of range. It must be <= 1GiB. Received 9_007_199_254_740_991

}

This error occurs since nodejs version 18 because the implementation for the computation of the high watermark in node streams changed. In nodejs v16 the hight watermark value was overriden with the max allowed value (1GB), In nodejs v18 an error is thrown if the max value is exceeded.

To fix this error the default value in OutputDocument.js bufferSize should be changed from currently 9007199254740991 to 0x40000000 (1GB)

Thanks for testing. Fixed by commit d9b5b9e.

When this fix will be present in beta version?

Could you make new version of pdfmake? I need use node 18
