Incorrect test: 07_fft_fft_conjugate

[tanakarin]

Hello,

I think I may have found a bug in 07_fft_fft_conjugate.

The first issue is that the conjugate is being calculated in each recursion of the fftCooleyTookey function , even though the FFT is being computed recursively. I think this can be resolved by calling correctFft instead of fftCooleyTookey in cpu.cc.

The second issue may be that the one-shot prompt does not support the conjugate.

Could you please check this when you have a moment?

Thank you.
