Currently `nulstr_contains` returns a boolean, making it difficult to identify which of the input strings matches the "needle". Adding a new `nulstr_get()` function, returning a const pointer to the matching string, eases this process and allows us to directly re-use the result of a call to this function without additional processing or memory allocation.
