Feature Request / Improvement

First, thanks for iterating quickly on the iceberg-go implementation. This is going to be very useful for us and make integrating with Iceberg easier. We're currently doing active development using iceberg-go to write to Iceberg and the main feature gap based on the latest version is the support for write positional delete files.

I realize that there are more missing features that are likely being worked on but do you have an idea of the priority of the support for write positional deletes? Also, if we wanted to contribute the feature to the project, do you have pointers or guidance that would be helpful?
