Title: make hann() the function and hanning the alias

pedantic, but the window is named "Hann". "Hanning" is erroneous, from being confused with Hamming. Also, scipy.signal documentation lists "hann", not "hanning". https://github.com/scipy/scipy/blob/4e4c8c98802698556d0b02aebab662f72f7cf19b/scipy/signal/info.py
