Sidenote, we dont have a way to read puffin files in python. I saw this PR from iceberg-rust, apache/iceberg-rust#892
Perhaps this will be a good candidate for pyiceberg_core

[Fokko]

I want to try using the Python roaringbitmap API first, otherwise, we can go the Iceberg-Rust route.

Looks like V3 is not supported on the pyiceberg side
