Wrap sorting functions

[ejmeitz]

Wrap sort and argsort.

These are both currently available in the cupynumeric/operators and should be easy to add.

NDArray sort(NDArray input, std::optional<int32_t> axis = -1, std::string kind = "quicksort");

NDArray argsort(NDArray input, std::optional<int32_t> axis = -1, std::string kind = "quicksort");
