**New Features**
- "Validation of instances" (1) in https://github.com/leon-richardt/python-repetita-parser/commit/9b4d5a65ce3eb213623b9c8c64e7be5c73515130 and
- "Keep paths from which objects were built as member objects" (2) in https://github.com/leon-richardt/python-repetita-parser/commit/b3430e7fff53144fe3ad78998b1a417738c92e8d
- Implementation of this feature resulted in the introduction of a `Demands` wrapper object which makes this a breaking release. This allows us to more easily introduce new features without breaking compatibility in the future.
