Feature description

The processing algorithm for clipping point clouds can be used to extract a subset of a remote hosted COPC dataset.
When doing so it seems it is downloading more than what required, probably the whole dataset. It would be nice if it would only download the regions that are required.

As the requests are not sent through QGIS, but through pdal_wrench, it is not easily possible to actually check the network requests, so my assumptions are based on drawing a polygon on a very small subset of points that are rendered in QGIS almost instantly whereas using this polygon with the pdal:clip algorithm is not finished after 10 minutes.

Clipping a remote copc.laz file using Point cloud data management/Clip in the Processing Toolbox also does not work for me. QGIS version is 3.36.2 Maidenhead. OS is Windows 11.

I thought setting the Cropping extent to "Use Current Map Canvas Extent" would work. But it doesn't.

Would be great to have this feature so multiple analysts can just extract data from specific regions.
