This function creates a time-vs-frequency plot image for analyzing a signal s time-evolving
frequency content. The signal is x, an analysis window of window_size samples is stepped
through the time extent of the signal, and Fs is the sample rate in Hz. A color-coded
logarithmic plot is generated of the top 30 dB of the frequency response magnitude a color
bar at the bottom left of the plot shows the color-coding of the dB values. The time waveform
x is plotted to the left of the time-frequency plot that coincides with the center time
of the analysis window used to produce the time-vs-frequency plot to the right.
