Error slicing LindiH5pyDataset with compound dtype

[stephprince]

I get a TypeError: Compound dataset /processing/optotagging/optogenetic_stimulation/timeseries does not support selection with slice(None, None, None) when attempting to get the html representation of a DynamicTable with a compound dtype when using Lindi. Using the local NWB file or streaming with remfile causes no error.

I think an additional case may need to be added for indexing into a LindiH5pyDataset with compound dtype using None values.

Code to reproduce:

import pynwb
import lindi
import remfile
import h5py

# load from remote nwb file
file = remfile.File("https://dandiarchive.s3.amazonaws.com/blobs/d5f/747/d5f74779-e41e-43af-b32c-1310e996a623")
f = h5py.File(file, 'r')
nwbfile = pynwb.NWBHDF5IO(file=f, mode='r').read()

stim_table = nwbfile.processing["optotagging"]["optogenetic_stimulation"]
stim_table._repr_html_()  # this works

# load from lindi file (same file as above, though any ogen nwbfile in dandiset 000253 should reproduce)
f = lindi.LindiH5pyFile.from_lindi_file("https://lindi.neurosift.org/dandi/dandisets/000253/assets/b305ccec-fa84-445e-aea5-0126d6eff558/nwb.lindi.json")
nwbfile = pynwb.NWBHDF5IO(file=f, mode='r').read()

stim_table = nwbfile.processing["optotagging"]["optogenetic_stimulation"]
stim_table._repr_html_()  # this errors
