HomeAssistant 'Problem finding attribute: 'duration'' in logging about pyhik

[Mincka]

This issue was also troubleshot here:
Supergiovane/node-red-contrib-hikvision-ultimate#16

The exception is thrown here because the duration eventType is unknown from sensor map.

This is a special event type to notify the beginning and ending of the target moving inside the zone for Intrusion Detection (aka FieldDetection). Its parsing is more complicated since the linked events are in a list:

<DurationList>
  <Duration>
    <relationEvent>fielddetection</relationEvent>
  </Duration>
</DurationList>

Maybe it's useful if you catch up the feed in the middle of an event. The receiver knows there are some kind of events still in progress.

From what I see in the linked issue, it should not be useful for HA since there are already fielddetection events with the states active then inactive. In this case, the easy fix would be to add duration to the sensor map but ignore its processing (return directly in process_stream.

I'm short on time these days to implement fixes, but can usually make time to review and merge a PR if someone wants to take a stab at it.

Fixed with PR #79.
