Siphon default regex in siphon/catalog.py fails for days 30/31

[pjpokran]

Siphon routine filter_time_nearest was returning the wrong times for days 30 and 31 of a month. I believe the problem is line 44 of siphon/catalog.py. The default regular expression is currently

default_regex = re.compile(r'(?P<year>\d{4})(?P<month>[01]\d)(?P<day>[012]\d)_'
                           r'(?P<hour>[012]\d)(?P<minute>[0-5]\d)')

which only accounts for days 01 through 29. To include days 30 and 31, you need to add a 3 to the day part:

default_regex = re.compile(r'(?P<year>\d{4})(?P<month>[01]\d)(?P<day>[0123]\d)_'
                           r'(?P<hour>[012]\d)(?P<minute>[0-5]\d)')

Working on a pull request with the fix.
Cheers. Pete
