When plotting multiple topographies, the contour lines seem to be drawn independently for each topo

[mmagnuski]

When plotting multiple topographies, the contour lines seem to be drawn independently for each topo. This is not necessarily a bug, but it may be unexpected - different contour levels per topo can be misleading. vmin and vmax are set identically for all topos, so the same could be done for contours.

[i will try to add a reproducible example later]

times = np.arange(0.35, 0.8, step=0.025)
clst.plot(picks=[0, 1, 2], time=times)
