Write test that verifies the images and general snn computation/results computation is correct.

• [x] Ensure the graphs are outputted to json correctly after stage 2. (Overwrite stage 1).
• [x] Ensure the network propagation is applied over the list of "nx_LIF" objects. (Just check they change over time, lateron, check if the SNN behaviour makes sense.)

Verify the output image name contains the timestamp in:

    run_config_to_filename(run_config)
    # TODO: Ensure output file exists.
    # TODO: Verify the correct graphs is passed by checking the graph tag.

    # TODO: merge experiment config, run_config into single dict.
    if run_config["simulator"] == "nx":

        if run_config["export_snns"]:
            # Output the json dictionary of the files.
            filename = run_config_to_filename(run_config)
            print(f"Exporting image:{filename}\n")

            output_stage_json(
                experiment_config,
                graphs_stage_2,
                filename,
                run_config,
                stage_index,

• [x] Modify Experiment_runner to also allow running a specific run_config.
• [x] Write test that verifies the json results match that of the Alipour results.
• [x] Include explicit check of nodecounts and nodenames dict equality to verify results more explicitly.
• [x] Include if passed =False then raise exception.
