Interior rings not working properly

[fitoprincipe]

Hi. I have a kml with a polygon that contains 2 interior rings

I leave it here (for reproduction purposes)

<?xml version="1.0" encoding="utf-8" ?>
<kml xmlns="http://www.opengis.net/kml/2.2">
<Document id="root_doc">
<Folder><name>test</name>
  <Placemark>
    <Polygon>      
      <outerBoundaryIs>
        <LinearRing><coordinates>-93.7426720226024,57.4519411370713 -93.6051809086549,49.4316261567984 -80.8643376828499,49.5232868994301 -81.2309806533767,57.4519411370713 -81.2309806533767,57.4519411370713 -93.7426720226024,57.4519411370713</coordinates></LinearRing>
      </outerBoundaryIs>
      <innerBoundaryIs>
        <LinearRing><coordinates>-91.8663227028478,56.050879726904 -91.7704563496718,53.9897531336206 -90.1407283456804,54.0856194867966 -90.0927951690924,56.002946550316 -91.8663227028478,56.050879726904</coordinates></LinearRing>
      </innerBoundaryIs>
      <innerBoundaryIs>
        <LinearRing><coordinates>-85.4912102166459,55.90708019714 -85.4912102166459,54.0376863102086 -83.8135490360665,54.0856194867966 -83.9094153892425,55.90708019714 -85.4912102166459,55.90708019714</coordinates></LinearRing>
      </innerBoundaryIs>
    </Polygon>
  </Placemark>
</Folder>
</Document></kml>

and the code to verify the error:

import fastkml
testkml = Path("test.kml")

with open(testkml, encoding='utf-8') as f:
    kml = fastkml.KML.class_from_string(f.read().encode("utf-8"))

doc = kml.features[0]
folder = doc.features[0]
placemark = folder.features[0]
pol = placemark.geometry

print(len(list(pol.interiors)))
# returns 1 when there are clearly 2 interior rings

I'd love to contribute and fix it myself, but I first need to understand how the package works internally and I don't have much time to do that.

Thanks

@fitoprincipe can you pull develop and test again?

Perfect, it works! Thanks @cleder 😃
