These are still not implemented as per #862 though all the other functions in the table there are now implemented for integer types.

These can be implemented in terms of Flint's fmpz_root function which returns an int if the root is exact.

We have is_power, is_prime_power, is_prime_power_with_data, is_perfect_power, is_perfect_power_with_data all native for ZZRingElem. I believe that resolve the issue.
