Problem

There's align_xlabels and align_ylabels to align the x and y labels, but no align_titles; this would be useful e.g. for

frompylabimport*fig,axs=subplots(1,2,subplot_kw={"xlabel":"x","ylabel":"y","title":"t"})axs[0].imshow(zeros((3,5)))axs[1].imshow(zeros((5,3)))fig.align_labels()

Proposed solution

Add Figure.align_titles.
