Property silently dropped

[Jaca]

In the RFC it says that Applications [...] SHOULD NOT silently drop any components as that can lead to user data loss. If you run this:

from icalendar import Event

ics = b'\r\n'.join([b'BEGIN:VEVENT',
                    b'X-APPLE-RADIUS=49.91307046514149',
                    b'END:VEVENT'])
print(Event.from_ical(ics).to_ical())

it outputs in b'BEGIN:VEVENT\r\nEND:VEVENT\r\n', so the X-APPLE_RADIUS property is lost

Interestingly, if you run:

from icalendar import Event

event = Event()
event.add(
    "X-APPLE-RADIUS",
    "49.91307046514149",
)
print(event.to_ical())

it outputs b'BEGIN:VEVENT\r\nX-APPLE-RADIUS:49.91307046514149\r\nEND:VEVENT\r\n', which is correct. The problem seems to be in the parser.
