Repository reorganisation and semantic versioning
Address issue #24 (closed) with:
- change versioning to semantic versioning with e.g., prod6 being "6.0.0" (this means a directory renaming plus a renaming of all version strings in the json files)
- remove directories validated_model and verified_model (all values in this repository should be validated and verified)
Additionally:
- fix typos reported by cspell (as part of pre-commit)
