Summary of ChangesHello, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request significantly enhances the library's annotation parsing capabilities by integrating a new parser for EMPAIA-formatted JSON files, allowing for the extraction of both polygon and point annotations. Alongside this new feature, the project's version has been updated, and new contributors have been acknowledged. Minor code improvements were also applied to an existing parser for better consistency and type hinting. Highlights

Code Review
This pull request introduces a new EMPAIAParser for handling EMPAIA format annotation files, supporting both polygon and point features. The changes include the parser implementation, integration into the package's __init__.py, and comprehensive unit tests. The project version has been updated to 1.3.1, and new authors have been added. Feedback includes suggestions to improve efficiency in EMPAIAParser.get_polygons by directly using coordinate tuples for shapely.Polygon construction and to enhance the robustness of polygon assertions in tests by verifying the full closed coordinate sequence.

For improved efficiency and more idiomatic shapely usage, it's better to create a list of coordinate tuples directly, rather than creating intermediate shapely.Point objects. The Polygon constructor is optimized to work with sequences of tuples.

The current assertions only check the first three points of the polygon's exterior. A shapely.Polygon is a closed ring, so its exterior.coords will have the first point repeated at the end. It's more robust to assert the full sequence of coordinates to ensure the polygon is correctly formed and closed.
