move pdal python support into a new package

Description

Currently pdal package has a lot of dependencies including Python3 and related packages, see https://trac.osgeo.org/grass/ticket/2732#comment:29. Python3 dependencies will enlarge significantly GRASS Windows standalone binaries since GRASS uses Python2 only.

Would be useful to split current package into pdal and python3-pdal to avoid Python3 dependency for core pdal package (similarly to other packages like gdal, python3-gdal, etc.)

I wonder why setup.hint (1) contains dependencies like python3-numpy, python3-gdal, and python3-matplotlib. In the package I found only bin, include and lib directories, nothing seems to be Python related here. Thanks for clarification in advance.

Same applies to GRASS - it also introduces a python2 dependency to QGIS3…

Right. But, well, it's not answer for the question why there is for pdal Python3 dependencies.

the question why there is for pdal Python3 dependencies

PDAL both embeds and extends Python, and it is built against Python3 for OSGeo4W, not Python2. The pdal-python package will not work against Python2. There is some background on the topic at https://github.com/PDAL/PDAL/issues/1478

PDAL depends upon Numpy when it extends Python.

The matplotlib dependency is a convenience for the PDAL workshop example https://pdal.io/workshop/exercises/python/histogram.html
