Describe the bug r.in.lidar does not read .laz 1.2 LiDAR files (

To Reproduce Steps to reproduce the behavior: 1.Download LiDAR data from USGS Lidar data download site https://www.usgs.gov/the-national-map-data-delivery/gis-data-download

  1. convert LAZ 1.4 LiDAR point cloud data to LAZ 1.2 data using pdal translate --writers.las.format="1" lidar14.laz lidar12.laz
  2. r.in.lidar -o --verbose lidar12.laz output=test_meanground class_filter=2,20
  3. ERROR: Unable to open file lidar12.laz as a LiDAR point cloud

Expected behavior Expected behavior in this chase would be the creation of a mean ground raster layer at the resolution in the region settings I suspect that GRASS 8.3.0 for windows was not compiled with the LAZ libraries in LibLAS Screenshots

System description (please complete the following information):

Additional context Add any other context about the problem here.

Did you already try https://grass.osgeo.org/grass-stable/manuals/r.in.pdal.html which is way more modern?

r.in.pdal is not compiled for the Windows standalone installer for 8.3.0. The option is greyed out. r.in.pdal is great, on Linux ( on my home computer :-))
