Single section vasculature fails to load due to empty connectivity

[eleftherioszisis]

I tried to load an one section vasculature dataset, but MorphIO doesn't load it due to the empty connectivity dataset.
test_single_section_sg.zip

from morphio.vasculature import Vasculature

v = Vasculature('test_single_section.h5')

Traceback:

---------------------------------------------------------------------------
