bug: between breaks if RDATE is an interval

[natashamm]

Describe the bug

between breaks if RDATE is an interval. I'm not sure if it is an issues with dateutil or recurring events.

To Reproduce

import datetime
import recurring_ical_events
import pytz

today = datetime.datetime.now(pytz.timezone("America/Vancouver")).date()
future = today + datetime.timedelta(days=365)
for event in cal_i.walk("VEVENT") + cal_i.walk("VFREEBUSY"):
    if event.has_key('RDATE'):
        if (event.has_key('RDATE')):
            recurring_ical_events.of(event).between(today - datetime.timedelta(days=60), future)

Version:

• add an ICS file, example:
  

  python-recurring-ical-events/test/calendars/issue-15-duplicated-events.ics

  Line 1 in f4a90b2

  BEGIN:VCALENDAR

• add a test, example:
  

  python-recurring-ical-events/test/test_issue_15.py

  Line 21 in f4a90b2

  def test_sequence_is_not_present(calendars):

• fix the bug and ensure the test code passes

Thanks for reporting this @natashamm! #74 is related. I like that there is actually a use-case for this!

Hi @natashamm. sorry - this was a wrong statement! I read EXRULE.

@natashamm, this should be fixed in v2.1.0. Can you confirm this to close this issue?
