Possible duplicate elements or evaluation error

[dhuber23b]

there are some duplicate annotations. For example, a single wall might be annotated by two duplicate elements that have slightly different poses, perhaps off by 0.01 in translation. This occurs pretty frequently in the dataset. For example, you can try scene 0137e4fcdafddcd21b84f4bbcaa4d32f_f0_r4_1 and run ground truth against ground truth. For the voxel track, I got translation_error of 0.0028, rms_points_error of 0.0044, etc., when they should both be 0.
