Load default values for settings panels from json

[nesnoj]

I'm currently adding settings values for the panels which need to be loaded on startup. I've uploaded the format with dummy values (most of them are the same as in your current file) to the Wolke which you can already use for testing.

Two things:

1. I added a new attribute future_scenario to the sliders, there should show up as extra markers if the attribute exists.
2. Question: In the panel settings the attribute "start" defines the startup value for the sliders. I'd also like to define (in my file) which switches are on by default, which attribute shall I use?

2. Maybe simply set "start": true

Nice that you use current structure - this would make it easy for us to merge JSONs. @Josephine-Marie you could use merge_dicts (currently in charts.py - we should move it to utils.py though) from @josihoppe therefore.

I added default values for the switches and updated the energy_settings_panel.json

BTW, there's a bug in the definition @Josephine-Marie, see #270

General note: I omit elements without any control functions in the files, i.e. the info boxes.

I'll add an additional attribute disable (according to ion range slider API) for disabling a slider, could you please adjust the formy.py accordingly (if needed)?

And please remove the biomass slider s_b_1 from the energy_settings_panel.json.

@Josephine-Marie Panel settings added to DP version 2023-07-03

Electricity and heat is complete. Traffic is filled with dummy values, but the format is complete and ready for takeoff :rocket: .

BTW, the settings are produced here, that might be helpful for the dynamic adjustments you're working on..
