Issue importing fixture data from json: "expected object at the top level"

[dmakovec]

While attempting to run fregot over a GCP resource policy library I'm building (based on https://github.com/forseti-security/policy-library), repl fails to start, with a parse error while attempting to load from a valid fixture JSON file.

opa loads the file's contents into the array data.test.fixtures.gcp_bq_c002_dataset_location.assets

fregot repl policies/lib policies/validator
fregot (parse error):
  "policies/validator/test/fixtures/gcp_bq_c002_dataset_location/assets/data.json" (line 1, column 1):
  parse failed:
