feat: Implement Type-aware purity analysis and integrate boundary and enum extractor

[Muellersen]

Summary of Changes

1. Integrated enum and boundary extractor from Nils bachelor's thesis. But unfortunately I had to disable the enum extractor for generating safe ds stubs, as there are some errors. For Example types like multiple_types : int, bool are extracted as ["True", "False"]
2. Integrated and wrote new tests for the enum and boundary extractors.
3. Integrated the purity analysis from Lukas bachelor's thesis. Can still be run by passing --old_purity_analysis as cli argument.
4. Implemented a type aware purity analysis which uses the typeextractors types to improve the purity analysis of Lukas.
5. Added the tests of the purity analysis from lukas and wrote a new test case to test the type aware purity analysis.
6. The purity results are passed to the stub generator which uses the results to annotate functions as either pure or impure.

depends on #185

It seems like I have to update astroid, in order to make the poetry-with-codecov (3.12) check work, as the current astroid version is not compatible with python 3.12. I will try to do that soon. :)
