[Bug Report] Detections with map feature ID decoding error

Describe the bug
Running interface.get_detections_with_map_feature_id under select map feature IDs throws a KeyError within the models/geojson file.

To Reproduce
mapillary.interface.get_detections_with_map_feature_id(1852672618623383, fields=[])

Returns KeyError as following:

Traceback (most recent call last):
  File "x.py", line 703, in <module>

    return f(*args, **kwargs)

    self.geometry = Geometry(feature["geometry"])
  File "..\mapillary\models\geojson.py", line 211, in __init__
    self.type: str = geometry["type"]
KeyError: 'type'

The returned GeoJSON from the API is in the form:

Clearly we see features in Mapillary without attached geometry, but still picked up by the map feature API.
It's unclear what the expected behaviour is here, otherwise I would have submitted a PR. 😥

Expected behavior
Detections returned as usual.
Unclear how to handle detections without any geometry.

Screenshots

Additional context

Reproduce the call to mapillary.interface.get_detections_with_map_feature_id with fields=[] and trace it through interface.py, controller/detection.py, and models/geojson.py. Inspect how Geometry handles the empty geometry object, clarify the intended returned representation, and consider the issue complete when this response no longer raises KeyError and the expected behavior is covered.
