zooniverse/aggregation-for-caesar: Version 5.1.0

Version 5.1.0 A new minor version release for aggregation, here are the new features: Major changes A .exe or .app version of aggregation-for-caesar is now available for Windows, MacOS (Intel), and MacOS (ARM, e.g. M1, M2, etc). Users can now interact directly with the GUI without a local Python install. Both an extractor and reducers have been added for polygon/freehand tools, along with a user guide for these tools. Minor changes The organisation of the documentation has been reworked for clarity. The time when the classification was created is now available for reducers. The progress bar can now be hidden. A bug where numpy data types appeared in the final extractions/reductions has now been fixed, and tests have been added to prevent it in future.
