v0 Curation does not throw away rejected units in the fetched sorting

[shijiegu]

Describe the bug
v0 Curation does not throw away rejected units in the fetched sorting.

To Reproduce

import spyglass.spikesorting.v0 as sgs
key = {"nwb_file_name":'eliot20221022_.nwb',
       "waveform_params_name":"default_clusterless",
       "sorter":"mountainsort4",
       "sort_interval_name": '02_Seq2Session1',
       "sort_group_id": 0,
       "curation_id":1}

sorting = sgs.Curation.get_curated_sorting(key)

There will be 12 units in the sorting. However, 4 units are rejected in the label.

(sgs.Curation & key).fetch1("curation_labels")

Expected behavior
Rejected units are removed from the sorting.

Spyglass spikesorting v0 does not make a spikeinterface spikesorting object for each curation. The information for the curated units can be accessed with (sgs.CuratedSpikeSorting() & key).fetch_nwb()[0]['units']. If you need something specific to the sorting object, see the code for Curation.save_sorting_nwb() for example of how to access and parse
