WKB with non-2D dimensions doesn't follow ISO encoding

Definitely not on purpose...thanks! Today (hopefully) geoarrow is getting its own Arrow-native WKB encoder and I'll make sure it does proper ISO output.

Not sure if you're aware of it, but there are GeoParquet & GeoArrow OGR drivers sitting at OSGeo/gdal#5477 if you want to do some interoperability checks. I noticed that a bit by chance because the drivers just use OGR WKB import that happily ingests that non-ISO WKB as it is the same as the PostGIS EWKB (without the SRID flag)

Yes, it's very exciting! I can and will check to make sure the arrays generated can be read (and that geoarrow can read the OGR-generated arrays)...right now I'm rewriting pretty much all of it to use the C Data interface and live in mostly header-only C++ (so that it can get reused in Python and maybe elsewhere if it's good enough), which will probably take another week or so to do properly.
