Add ghmap to GH Archive list

[uhourri]

I would like to propose adding ghmap to the list of projects built on top of the GH Archive.

ghmap is an open-source tool that maps raw GitHub events (such as those provided by GH Archive) into higher-level actions and activities, enabling large-scale analysis of contributor behavior and workflows.
It has been used in academic research to construct a dataset covering 3 years of activity in the NumFocus ecosystem (180K+ contributors, 2.8K+ repositories).

Links:

• GitHub: https://github.com/uhourri/ghmap
• PyPI: https://pypi.org/project/ghmap
• Paper: Y. Hourri, A. Decan, and T. Mens, A Dataset of Contributor Activities in the NumFocus Open-Source Community, MSR 2025

ghmap directly builds on GH Archive data to perform semantic event transformations, which fits well with the scope of this list.

Thanks for maintaining this great resource!
