This branch adds the option to consider simplified distribution grids in eTraGo.
The parametrization of the simplified distribution grids has to be provided in a csv file.
I created it with several eDisGo-simulations. Later on, that part will be included in eGo.

@KathiEsterl: I know that we still have to clarify some things, and also when we want to merge. Anyhow, I thought it helps to already have this draft PR.

I have made a few minor updates to the documentation.

Additionally, I noticed that the docstrings in appl.py do not yet include the market_optimization and the new distribution_grid functionalities. Since you are more familiar with the respective parameters, could you please add them, @ClaraBuettner ?

Yes, sure I will add a description there.

I reviewed the code and verified its plausibility.
I ran several test cases using different settings and also evaluated the new plotting functions.
Additionally, I went through the updated documentation.
I just didn't conduct bigger calculations, but I guess we will do this anyhow soon.
Therefore, I guess the PR is ready to be merged :)
