DALEXtra support for `censored` tidymodels / integration with `survex`?

Hi, I posted this issue over on `survex` but perhaps here it is more appropriate? 

https://github.com/ModelOriented/survex/issues/98

Now that `tidymodels` covers survival analysis ([https://censored.tidymodels.org/](https://censored.tidymodels.org/)), perhaps the methods from `survex` could be used in with the extensions here for deriving feature importance from censored tidymodels?
