Output user-friendly report of GO-CAM stats

[pgaudet]

We would like a report similar to
https://release.geneontology.org/2025-10-10/reports/assigned-by-gorule-report.html

or https://go-cam-browser.geneontology.org/

		Group 1	Group 2	Group 3
1	Number of models
2	number_of_unique_genes
3	number_of_unique_references
4	number_of_unique_pmid
5	number_of_activities

And a similar report by curator (that could also be filtered by group)
