Feature/energy system max demand fulfillment fix

[smartie2076]

Hi @ciaradunks I found the issues why the check did not work. I commited in very small batches, so that you can check where what went wrong. I also added a pseudo-benchmark test that assessed whether the check was running in general.

There are two failing tests now.

This one is interesting, as timeseries_peak seems to be missing. All non-dispatchable PV assets have this parameter, so what could this be? It is the exception that we define a fuel source in energyProduction.csv. There must be an exeption for this case.

FAILED tests/test_benchmark_KPI.py::Test_Economic_KPI::test_benchmark_Economic_KPI_C2_E2 - KeyError: 'timeseries_peak'

And

FAILED tests/test_input_folder_parameters.py::test_input_folder_csv_files_have_required_parameters[D:\\PycharmProjects\\mvs_eland\\tests\\benchmark_test_outputs\\validity_chec
k_insufficient_capacities\\inputs]

Which I think is unimportant.

My last commit now fixed the failing benchmark test. This means, however, that you need to adapt your pytests to also cover fuel sources and their exceptions.

Edit: Ie. you need a seperate test for ENERGY_PRODUCTION: {},, where you run the function for one dispatchable fuel source and one non-dispatchable renewbale source. (Btw, I did the if-loop based on TIMESERIES_PEAK which is not as beautiful as on DISPATCHABILITY, but it does the job).
