[Bug]: Inaccurate critical error for 2D SpikeEventSeries

[stephprince]

What happened?

According to the nwb-schema, a SpikeEventSeries can have dimensions [num events, num samples] when it contains data from a single electrode. The other option is to have dimensions [num events, num channels, num samples] if it has data from multiple electrodes.

However if an NWB file contains a 2D SpikeEventSeries, the inspector will return a critical error that the second dimension does not match the length of electrodes:

0  CRITICAL
===========

0.0  createESandSES.nwb: check_electrical_series_dims - 'SpikeEventSeries' object at location '/acquisition/spikedata1'
       Message: The second dimension of data does not match the length of electrodes. Your data may be transposed.

I think the check should be updated to warn about potentially transposed data only if a SpikeEventSeries has 3 dimensions.
