Some zipcode polygons are 3D lists

[nog642]

The polygon for 44122 (using simple_zipcode=False) returns a 3D list, unlike most zipcodes. The regular 2D list is itself the only item in an outer list. The 2D list inside also seems much too short to be a good polygon for this zipcode.

I have uszipcode==0.2.2 installed in a virtualenv.

>>> search = SearchEngine(simple_zipcode=False)
>>> search.by_zipcode('44122').polygon
[[[-81.549838, 41.478182], [-81.549829, 41.474945], [-81.549883, 41.474739], [-81.550029, 41.474493], [-81.550482, 41.475187], [-81.550473, 41.477716], [-81.549838, 41.478182]]]

The expected behavior is that it returns a 2D list with many more points than that.

Other zipcodes I've found with the same issue (not a complete list):

• 31632
• 49426
• 45801
• 60605
• 22180
• 08540
• 01588
• 55901

Thank you, I will check the data source I crawled for polygon and update it.
