Paul Dreik 725ca010e7 add ndjson fuzzer (#1304)
* add ndjson fuzzer

* reproduce #1310 in the newly added unit test

Had to replace the input, because:
1)
the fuzzer uses the first part of the input to determine
the batch_size to use, so that has to be cut off

2)
the master now protects against low values of batch_size

I also made the test not return early, so the error is triggered.
