Error in check_fix_rrule (AttributeError: 'str' object has no attribute 'items')

Hi,

I just wanted to try this integration, but sadly I'm getting the following error repeatedly.

Log:

Let me know if I can provide you with any further details.

I hope you can fix this issue soon, thank you in advance :)

After some debugging I found out that event["RRULE"] was an array for one of my calendar events.

This quick and very dirty fix is now working for me (changes at == START OF FIX ==):

# inside custom_components/isc/sensor.py, check_fix_rrule
for event in calendar.walk('vevent'):
    if("RRULE" in event):
        # == START OF FIX ==
        if(isinstance(event["RRULE"], list):
            event["RRULE"] = event["RRULE"][0]
        # == END OF FIX ==
        if("UNTIL" in event["RRULE"]):
            # ...

Sadly (as of right now) I have no idea how this can be handled correctly, otherwise I would have created a PR.
But maybe my findings help you solve the bug.

Hmm this seems to be an issue with the underlaying iCalendar .. would you open your ticket there? Also: I'd totally accept that pull request. ..
