Final update to bump python dependency versions and change the Readme

[bobvdvelde]

Dependency updates + fix of breaking changes & a 'no longer maintained' Readme.md

Closes all other PRs 🎉

---

A final PR to 'close them all'. 👋 🫡

Assumptions

This is the farewell PR for OSD2F maintainance. It assumes anyone interested in reusing/extending the code deserves a tidy final release with (at least at the time of publishing) up-to-date depencies and working build system.

For pragmatic reasons, the javascript side is not fully updated, as this would entail a major migration for the Vue framework (v2->v3).

Information about the status of this repository has been added to the readme (preview: here )
