[pdal] In two LAZ files "WARNING: files have different point types: 3 vs 7"

[Ulises Ibarra]

Hi Andrew, thank you.

In the input.laz file I have:
    "header_size": 227,
    "major_version": 1,
    "maxx": 583635.928,
    "maxy": 3596868.333,
    "maxz": 1353.431,
    "minor_version": 2,
    "minx": 578122.935,
    "miny": 3593497.807,
    "minz": 1240.855,
    "offset_x": 570000,
    "offset_y": 3590000,
    "offset_z": 0,
    "point_length": 34,
    "project_id": "00000000-0000-0000-0000-000000000000",
    "scale_x": 0.001,
    "scale_y": 0.001,
    "scale_z": 0.001,
    "software_id": "PDAL 2.7.1 (Releas)",

But in the output.laz file I have:
"header_size": 227,
    "major_version": 1,
    "maxx": 583635.928,
    "maxy": 3596868.333,
    "maxz": 1318.891,
    "minor_version": 2,
    "minx": 578122.935,
    "miny": 3593497.807,
    "minz": 1206.324,
    "offset_x": 570000,
    "offset_y": 3590000,
    "offset_z": 0,
    "point_length": 34,
    "project_id": "00000000-0000-0000-0000-000000000000",
    "scale_x": 0.001,
    "scale_y": 0.001,
    "scale_z": 0.001,
    "software_id": "lasmerge (version 191018)",

I mean: the same! "point_length": 34 "  --> 🥺
