Do you, good developer, want these notebook tutorial examples in the linopy repo?

Hi - I wrote a couple of linopy example notebooks on my github page [here](https://github.com/tpu-brunkhorst/TP_datascience_public/tree/main/linopy_examples)

One is a monthly energy portfolio model and the other is a sudoku puzzle solver :)

Let me know if you want one or both of these and I can try to step through the PR process.
