Status: ToricVarieties_project in Oscar and Julia

1. ToricVarieties_project should allow to access/switch among the following two oracles: (NConvex, CddInterface) and Polymake.
2. CddInterface is currently not functional in Julia, see e.g. https://github.com/homalg-project/CddInterface/issues/23.
3. Access to Polymake in Oscar will rely on a package equivalent to NConvex, i.e. a refreshed version of https://github.com/homalg-project/homalg_project/tree/871a7e41a089a4ad9b4315bdb45dedd8831f10f7/Convex. This is currently being discussed at https://github.com/homalg-project/ToricVarieties_project/discussions/74. This interface should follow the examples in https://github.com/lkastner/polymakejl4tv/blob/master/initial.ipynb.
4. Advanced functionality in the ToricVarieties_project relies on NormalizInterface. Currently, this package seems to be not functional in Julia, see e.g. https://github.com/gap-packages/NormalizInterface/issues/96.
