+ Initializes an EZAudioFFTRolling instance with a window size, a history buffer size, a sample rate, and an EZAudioFFTDelegate.

+ @param windowSize        A vDSP_Length (unsigned long) representing the size of the window (i.e. the resolution) of data that should be used to calculate the FFT. A typical value for this would be something like 1024 - 4096 (or higher for an even higher resolution FFT).
+ @param historyBufferSize A vDSP_Length (unsigned long) representing the length of the history buffer. This should be AT LEAST the size of the window. A recommended value for this would be at least 8x greater than the `windowSize` argument.
