Bug loading morphologies in release

Thank you for this amazing tool!

I tried to install both in Mac and CentOS Blender version 3.5 with the provided script, but it usually found issues with package versions in pip.
The only solution I got left was to use the release version. However, I noticed I was missing fragments of my SWCs.

After digging a bit in the code of the release, I found a bug in the function "update_section_parenting" in "2.80/scripts/addons/neuromorphovis/nmv/skeleton/ops/skeleton_construction_ops.py".

As it is in the released code, lines 58 and 66 compare the last and first indices of different sections and check if they are the same.
But the function should check whether the index and **parent** index of consecutive sections are the same.

Thus, modifying the mentioned lines to:
58:` if section.samples[-1].index == i_section.samples[0].parent_index:`
66:` if section.samples[0].parent_index == i_section.samples[-1].index:`
solves the issue.
