Plexon signal stream_ids are not cosistent across reads #1523

The problem is here:

https://github.com/NeuralEnsemble/python-neo/blob/315f485eb24c8d17aaebc5d6b56a336840913b66/neo/rawio/plexonrawio.py#L269-L275

We use set to form unique users group, enumerate over them to determine stream_index and use str(stream_index) as a stream_id. But this does not work because iterating over sets and determining sets is not deterministic.

yep. set is dangerous for that. np.unique() could be a better choice.

Fixed with a dictionary strategy in #1524. Closing.
