 ## Acknowledgments
 
 This project was initially developed in the context of the Programming Experience Seminar 2021/22 @ [hpi-swa-teaching](https://github.com/hpi-swa-teaching) and developed further in the context of the Reverse Engineering Seminar 2022 @ [hpi-swa-teaching](https://github.com/hpi-swa-teaching). Many thanks to my careful advisor [@marceltaeumel](https://github.com/marceltaeumel)! Furthermore, I'd like to thank [@tom95](https://github.com/tom95) and [@stlutz](https://github.com/stlutz) for their valuable feedback on the prototype.
