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

[James Klassen]

I don’t remember if the Pi zero 2 is 64 bit or not but it is likely running
a 32 bit (armhf) OS either way with 512MB RAM.

I have built PDAL from source on RPi4 (4GB) and RPi5 (8GB) no problem.
Both obviously aarch64.

My guess is PDAL would run fine on a Pi 0 for small datasets or streaming
mode if built somewhere else.
