fft_spectrum: Calculate fft amplitude and phase
In tsuda16k/noesis: What the Package Does (One Line, Title Case)

Calculate fft amplitude and phase

1	fft_spectrum(im, modify = FALSE)

`im`	an image
`modify`	if TRUE, amplitude value is log-rescaled, which is useful for plotting purpose

img = fft_spectrum(im_gray(regatta), modify = TRUE)
plot(img$magnitude)
plot(img$phase, rescale = TRUE)
