Hi,

I run into the following error when I want to concatenate a bunch of svg files as follows

svg_stack.py --direction=v --margin=100 Figure\ S1.svg Figure\ S2.svg Figure\ S3.svg Figure\ S4.svg Figure\ S5.svg Figure\ S6.svg Figure\ S7.svg Figure\ S8.svg Figure\ S9.svg Figure\ S10.svg Figure\ S11.svg Figure\ S12.svg Figure\ S13.svg Figure\ S14 Figure\ S15.svg Figure\ S16 > Figures_SI.svg

(Apologies for my delay.)

I think this may have been fixed by #14. Can you check this by running on the current main branch?
