TypeError when 'shape_dist_traveled' is empty

[RuiLoureiro]

When pygtfs tries to parse the following line:

shape_id,shape_pt_lat,shape_pt_lon,shape_pt_sequence,shape_dist_traveled
149554,38.742155,-9.102203,1,

I get the following error:

Failure while writing Shapes(shape_id='149554', shape_pt_lat='38.742155', shape_pt_lon='-9.102203', shape_pt_sequence='1', shape_dist_traveled=None)

TypeError: float() argument must be a string or a number, not 'NoneType'

Looking at the is_float_none method, it seems you were expecting float(None) to raise a ValueError, but it is raising a TypeError instead.

Would probably be solved by #65
