Outreachy Presentations for the December 2022 Round

The OCaml community participated in the December 2022 round of [Outreachy](https://www.outreachy.org/) internships. We had one intern work on a TopoJSON parsing library. This meeting was an opportunity for the interns to present their work and for the community to ask questions and was [originally announced on the discuss forum](https://discuss.ocaml.org/t/monday-6th-march-outreachy-intern-presentation-dec-22-round/11564/4).
