Chopping off one pixel at the end of each segment in EDPF::ExtractNewSegments()

https://github.com/CihanTopal/ED_Lib/blob/7f171db0321de67b12ee3d0558b0b1d60122000d/EDPF.cpp#L219

My fork is getting so refactored that it's a bit hard to translate back to original ED_Lib now, but I think the referenced line is in error. I think it should just say end, instead of end - 1.

The corresponding line in my code is here: https://gitlab.com/tobben/hpm/-/blob/b079a6f824984bc89cc7df5ed1247974fda99dbe/hpm/ed/EDCommon.c++#L33

The issue is easiest to see and to validate manually in very short segments. This is the edgeImage:

This is the validated segment when using end - 1.

This is the same segment with end - 1 changed to end:

Changing this makes EDCircles find more circles.

Please stop me if the copping of that last pixel is intentional, which it very well might be.

Ironically, from a top level view, the performance of my particular application got worse, since more (real) circles were found, that it had to filter away. I balanced this back by lowering LONG_ARC_ERROR in EDCircles.cpp.
