Support `__arrow_c_array__` in viz()

[kylebarron]

It would be nice to be able to visualize any array. Note that this should be before __geo_interface__ in the conversion steps.

You might want to do something like the following to ensure the field metadata isn't lost if extension types aren't installed.

if hasattr(obj, "__arrow_c_array__"):
    schema, _ = obj.__arrow_c_array__()

    class SchemaHolder:
        def __init__(self, capsule) -> None:
            self.capsule = capsule

        def __arrow_c_schema__(self):
            return self.capsule
        
    pyarrow_field = pa.field(SchemaHolder(schema))
    pyarrow_array = pa.array(obj)
