'PnW' durations are not supported

[Pedro Romano]

ISO 8601 allows durations with the format PnW for a given number of weeks, but aniso8601 doesn't support these.

I can confirm the issue. Sample output shown below:

>>> import aniso8601
>>> aniso8601.parse_duration('P1W')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "aniso8601/duration.py", line 37, in parse_duration
    return parse_duration_combined(isodurationstr)
  File "aniso8601/duration.py", line 120, in parse_duration_combined
    datepart, timepart = durationstr[1:].split('T') #We skip the 'P'
ValueError: need more than 1 value to unpack

Expected result would be:

>>> import aniso8601
>>> aniso8601.parse_duration('P1W')
datetime.timedelta(7)
