Feature request: Option to Save or Not Save Plots

Optionally Save HOPP plots

Every time HOPP is run, battery_output.png and generation_profile.png are created, which are not universally required. For both testing and docs building, this is unnecessary and requires additional teardown steps. Ideally, this should be a model input parameter.

https://github.com/NatLabRockies/H2Integrate/blob/d51a3cd99389be7b922f1c0329fbb3920cb94be3/h2integrate/converters/hopp/hopp_wrapper.py#L161C13-L168C21

Proposed solution

Include an option in the HOPP config (using https://github.com/NatLabRockies/H2Integrate/blob/main/examples/25_sizing_modes/tech_inputs/hopp_config_tx.yaml#L209) as an example, it could go in the simulation_options like the following, which would allow for the code modifications listed beneath.

#hopp_config_tx.yaml
...
config:
  simulation_options:
    cache: true
    save_figures: false
    wind:
      skip_financial: false

# h2integrate/converters/hopp/hopp_wrapper.py::161
            try:
                system = self.hybrid_interface.system
                save = self.hopp_config["config"]["simulation_options"]["save_figures"]
                plot_battery_output(system, start_day=180, plot_filename="battery_output.png" if save else None)
                plot_generation_profile(
                    system, start_day=180, plot_filename="generation_profile.png" if save else None
                )
            except AttributeError:
                pass

Alternatives considered

Currently these are included in the .gitignore, and to remove them locally I either delete them manually. In a separate testing work, their removal is part of a teardown phase, but the example itself is called in more than one place, so this is required in more than one place.

Additional context

Start in h2integrate/converters/hopp/hopp_wrapper.py around line 161 and review the HOPP configuration example at examples/25_sizing_modes/tech_inputs/hopp_config_tx.yaml around line 209. Trace the other places where the example is called, then verify that the new option controls creation of battery_output.png and generation_profile.png so testing and docs builds do not require teardown.
