local variable 'geometry' referenced before assignment

[crawld]

i'm getting the follow error with 0.8.2:

  File "/igniter/./app/app.py", line 79, in create
    unit = dt.BurnUnit.from_json(request.unit, request.firing_direction)
  File "/usr/local/lib/python3.10/dist-packages/driptorch/unit.py", line 80, in from_json
    polygon = read_geojson_polygon(geojson)
  File "/usr/local/lib/python3.10/dist-packages/driptorch/io.py", line 182, in read_geojson_polygon
    return geometry
UnboundLocalError: local variable 'geometry' referenced before assignment

the burn unit i give to DT is a union of Whale Pasture Main and Whale Pasture West in the attached geojson.
