Plot Bode
=====================================

:func:`sysplot.plot_bode` produces a two-panel Bode diagram from magnitude,
phase, and frequency arrays. Phase is automatically unwrapped and labelled
in multiples of π. The ``mag_to_dB`` flag switches between dB and linear
magnitude, and ``minor_ticks`` adds minor decade marks to the log frequency
axis.
