Function that plots cluster buses in a pandapower net

[Researcher-Retorta]

Hey,

I talked via email with Alexander Scheidler about my contribution regarding cluster visualization in pandapower grids.

The purpose of the update is to illustrate zones within the grid.
The function allows for the representation of these zones' buses in an electrical grid through colorful buses, with each color representing a distinct zone. Essentially, it's a modified version of "vlevel_plotly".

I believe this functionality significantly enhances our ability to visualize and analyze the grid into zones, providing valuable insights into resource aggregation and distribution.

I added an example in tutorials, which encompass 2 .ipynb files, 2 .py files, 1 Excel file and 1 .sqlite file.

Dear @Researcher-Retorta ,

Thank you for this contribution!

I am a bit confused why there is the file tutorials/traces with functions that create traces when we already have a file that includes functions for creating plotly traces.
