fafbseg.flywire.synapses.fetch_adjacency doesn't recognize lists as inputs

[jialumaomao]

In fafbseg/utils.py, we have the following function:
def make_iterable(x, force_type = None)And when passing a list, utils.make_iterable is called in `fafbseg/flywire/utils.py:

 if isinstance(x, navis.BaseNeuron):
    ids = [x.id]
 elif isinstance(x, navis.NeuronList):
    ids = x.id
 elif isinstance(x, (int, [np.int](http://np.int/))):
    ids = [x]
 else:
    ids = utils.make_iterable(x, dtype=np.int64)

But an error occurs, because the parameters do not match the function declaration.
