Durations with components in wrong order are parsed successfully

[Matti Niemenmaa]

The duration parser doesn't seem to care about the order in which the durations are given:

>>> aniso8601.parse_duration('P1D1Y1M')
datetime.timedelta(396)

>>> aniso8601.parse_duration('PT1S1H')
datetime.timedelta(0, 3601)

I would expect exceptions to be raised instead.

This is with aniso8601 1.1.0.

[Brandon Nielsen]

Fixed in 1.2.0.
