Support dpf composite backend 6.1 (23.2) and 7.0 (24.1) in parallel

[roosre]

closes #66 .

This PR is needed to support the new DPF Composites backend which uses supoperators instead of the Failure- and SamplingPoint Operator.
This is achieved by

• An implementation member was added to the composite model which refers to the actual implementation. The returned class is compatible with the used DPF server.
• A protocol is used to implement the Sampling Point class. This allows to distinguish between the support server versions but have an unique API. See sampling_point_types.py.
• Deprecation warnings were added where the composite_definition_label is used.
• helper functions where added to check the dpf server version (see server_helpers/_versions.py)
