TypeError raised when parsing gtin in 3.2.0

[yaser-fyndiq]

Hello,

I tried parsing the same gtin value in 3.1.0 and 3.2.0 and it seems that 3.2.0 is raising an unhandled exception. Maybe this is related to #292?

• With 3.1.0, it's working fine:

>>> import biip
>>> biip.parse("701197206489")

• With 3.2.0, it's raising TypeError
