python bindings: fetch method fails to retrieve online data via NDS1

The iterate method can obtain online data if you give it a start time of 0 and a duration as end time. But invoking the fetch method in this way does not work:

>>> import nds2
>>> nds2.fetch(['X2:ASC-CHARD_P_OUT_DQ'], 0, 10)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/opt/conda/base/envs/cds/lib/python3.10/site-packages/nds2.py", line 1628, in fetch
    return _fetch(params, gps_start, gps_stop, channels)
RuntimeError: An unexpected number of channels were received
>>> nds2.__version__
'0.16.12'
