`get` and `ids` functions do not work with tuples

[joni-herttuainen]

Did not test with Edges/EdgePopulation but I would assume the issue is the same as with Nodes/NodePopulation:

>>> circuit.nodes['sscx_neurons'].ids({'region': ['mc2_Column', 'mc3_Column']})
array([     0,      2,      7, ..., 163519, 163521, 163523])

>>> circuit.nodes['sscx_neurons'].ids({'region': ('mc2_Column', 'mc3_Column')})
array([], dtype=int64)

I am unsure if we explicitly specify that the input for OR needs to be given as a list but I'd expect it to work with other iterables, too.
