fix(python-bindings): added darwin duplicate rpath patch and fixed python rpath poiting

due to a current bug in meson-python duplicate rpaths are registered in the shared object files created by meson-python. The new masos dynamic loader refuses to load shared object files with duplicate rpaths. There is a small patch script which removes any duplicates. This is a temporary but effective fix (https://github.com/mesonbuild/meson-python/issues/813). Further, there was an issue due to mixed use of pure python and C++ code with name conflicts. This has been resolved so that both python and C++ code can be imported just find now.
