Following publication of the original article [1], one of the authors flagged that the images for Figs. 2 and 3 were swapped in the published article—Fig. 2 had the image meant for Fig. 3 and vice versa.

As such, the original article [1] has been updated to correct this error.

The publisher apologizes for any inconvenience caused.
