v0.2.5

• Return descriptive error if data extract is empty or incorrectly parsed.
• Handle case where 'tags' key in data extract is a JSON string (i.e. with escape characters).
  • This would fail previously due to attempt to .get() a string.
  • The use case was for flatgeobuf --> geojson deserialisation. Sometimes nested props are generated as JSON string in the GeoJSON. This could be during flatgeobuf generation, or during the fgb --> geojson deserialisation.
  • The workaround parses the 'tags' key as a dict, else skips the tags for a feature (if parsing fails).
