Durations with trailing garbage are parsed successfully

[Matti Niemenmaa]

Any nonsense can be put after a duration, and the parser will succeed:

>>> aniso8601.parse_duration('P1Dasdfasdf')
datetime.timedelta(1)

This also affects intervals that contain durations:

>>> aniso8601.parse_interval('2001/P1Dasdf')
(datetime.date(2001, 1, 1), datetime.date(2001, 1, 2))

>>> aniso8601.parse_interval('P1Dasdf/2001')
(datetime.date(2001, 1, 1), datetime.date(2000, 12, 31))

I would expect exceptions to be raised instead.

This is with aniso8601 1.1.0.

[Brandon Nielsen]

Fixed in 1.2.0.
