Current of accuracy testing for histogram CE implementation outputs csv tuples.
During https://jira.mongodb.org/browse/WRITING-27578 the analysis was done in a jupyter notebook connected to a mongodb instance.
To accomodate the analysis pipeline we propose outputing the accuracy testing results in json documents that can be inserted directly into a collection.
In addition, it is useful to include more information such as seeds for queries and data to expose more information regarding the simulation configuration.
