ENH: Add 'sat-multitaper' as method for vocalpy.spectrogram

[NickleDave]

More general name, less awkward, makes sense when we refer to other time-freq-reps, e.g. tf replacement, gammatone, et al.

[NickleDave]

Thinking about this more ...
Spectrogram is common enough that I think we don't want to change it.
Even other time-freq representations we use or will want to use are still (power) spectrograms: SAT uses a multi-taper spectrogram, soundsig/biosound uses a Gaussian window spectrogram. Even time-frequency replacement, as most widely used, still ends up giving you a power spectrogram, IIUC

Other things I will need to add presently are better described as features, e.g. gammatone

So: wontfix, for now

But what I think we should do is separate out the multi-taper spectral representation used by SAT and make it possible to call that as a spectrogram

[NickleDave]

I still don't like the name SpectrogramMaker but if most of what we use is a spectrogram then makes sense to keep it
