The spectrum template was not being instantiated by the current build,
so stale accesses to cfft_engine::n went unnoticed.
Replace direct accesses to the private cfft_engine member with the
public size() accessor. This restores spectrum compilation and allows
the upcoming VLA cleanup to be built and tested.
