Implement an example for pinch analysis through coupling `tespy` with `pina`

Resolves #ISSUE_NUMBER

I added the aspects from pina for pinch analysis and additional plotting functions. I also added comments for still needed functions as well as possibilities to connect to tespy. By now it can be seen as a seperated set of functions.

• [ x] Implement unit tests for the changes --> done as an example, as the implementation is currently by plotting
• [ x] For a new feature: Implement an example and a system test --> example as said above

I need help for those two aspects

• [ ] Update the documentation
• [ ] Update the changelog at docs/whats_new/* Additionally pina 0.1.1 is required. Add this the requirements

Hi @n-arth, thank you for pushing this topic! I'd suggest we meet and build a minimal example/integration with a tespy model (maybe using SimpleHeatExchanger instances to keep things simple). Best

Hi @fwitte I added the minimal example with the simple heat exchanger. Summarizing the previous messages and our conversations, there are the following aspects missing by now:

• [ ] Update the documentation
• [ ] Update the changelog at docs
• [ ] Include pint / the network units
• [ ] Include all heat exchanger types
• [ ] Create some automated tests (the generated plots have to be reviewed manually)
• [ ] add a commented example introducing pinch analysis and the functions
• [ ] add automatic checks for integrated heat pumps regarding the pinch analysis conditions
• [ ] add a new function to include any set of heat exchangers, in contrast to the heat pump with just two
