Segmentation Fault when parsing a .ply with property list uchar uint vertex_indices

[ManosAgelidis]

Hi, great repo! I was trying to simplify a .ply mesh which is causing a seg fault when executing the script. It seems to crash when it's executing this loop

I checked an example ply that I found online (https://www.artec3d.com/3d-models/bearded-guy-hd) vs my .ply and and I noticed that my .ply header is slightly different, in particular the header that doesn't work is like this (notice the uint in line 18)

vs the header that works

Any ideas as to where the problem might be coming from? thanks!
