Support for Apache Iceberg Table Format

[rupurt]

Howdy,

Are there any plans to support the Apache Iceberg table format? It's starting to emerge as the go-to open table format.

There is now basic support in rust via iceberg-rs

I am not actively working on an iceberg support, but will definitely be happy to accept a PR for this.

A quick glance on iceberg-rs suggests that it only implemented the metadata parsing part, which is far from a complete and usable iceberg implementation unfortunately.

@houqp no worries. I did some more digging and found a good thread on the progress. There's a fair bit of work being done but nothing ready atm apache/iceberg#5122
