Real FFT is broken

[auroranockert]

Only the 2-butterfly is defined for real FFTs and I am not sure it works. The expected result is that it should work.

Hi, I'd really like to use this library in a project, and wondering about fixing the FFT for reals. Any chance of fixing this? Or, I'm happy to have a go at fixing the missing 3 butterfly. Is it just a question of translating the relevant bit of code from kissfft?

Translating the butterflies from KissFFT should be enough.
