[BUG] Keypoints in CVAT not imported

Describe the problem

When importing data from cvat using the fiftyone.utils.cvat.import_annotation() function, all annotations with labels: classification, detections, polylines are loaded correctly. However keypoints are not loaded. Am I doing anything wrong here or is this a bug?

Code to reproduce issue

I've used the following code to import the data:

import fiftyone as fo
import fiftyone.utils.cvat as foucv

dataset = fo.Dataset(name="navigation", overwrite=True)

# Import annotations directly
foucv.import_annotations(
    dataset, 
    url="http://cvat.local",
    project_id=121,
)

With the following output:

 100% |█████████████████| 354/354 [73.0ms elapsed, 0s remaining, 4.8K samples/s]

As you can see the labels for field "keypoints" are not loading in.
