Could you please pay extra attention to the points below when reviewing the PR:

I'm a new contributor so pay attention to the coding standards applicable to this project along with achitectural rules etc.

Check list

• Check if the available input/update/output data suffices (check power-grid-model/power_grid_model_c/power_grid_model/include/power_grid_model/auxiliary/ input.hpp / update.hpp / output.hpp or in the documentation directly)
• If not, add the new data format to code_generation/data/attribute_classes/ input.json / update.json / output.json + run code_generation/code_gen.py
• Create a new component in a new power-grid-model/power_grid_model_c/power_grid_model/include/power_grid_model/component/[component].hpp file that at least inherits from Base, but in this case GenericBranch should inherit from Branch
• If necessary: add new enums or exceptions
• Create the necessary unit tests in power-grid-model/tests/cpp_unit_tests/test_[component].cpp
• Add the test_[component].cpp to power-grid-model/tests/cpp_unit_tests/CMakeLists.txt
• Add component to power_grid_model_c/power_grid_model/include/power_grid_model/all_components.hpp
• Not necessary for this component (If necessary update main_core/topology.hpp / input.hpp / output.hpp / update.hpp)
• Add component to code_generation/data/dataset_class_maps/dataset_definitions.json + re-run code_generation/code_gen.py
• Add validation test cases to tests/data
• Update input/update data validator for the new component: src/power_grid_model/validation/validation.py + add corresponding tests
