[pdal] Build/install pdal on raspberry pi zero 2

[Howard Butler]

I agree with Paul and would add that the shortest path to getting PDAL on an RPI is to use Conda. Otherwise you'll have to cross-compile it yourself on a more capable machine. 

Another Conda pathway is to use pixi instead of miniconda, etc. https://pixi.sh which kind of flips the whole conda environments thing on its head but still uses all the packages and their relationships from CondaForge to achieve it.

I wonder which architecture the Conda on Pi Zero installation is looking for - PDAL supports linux-aarch64, which I would have thought would have been the one but worth checking.
