Support writes to Bucket Partitioned Tables

[sungwy]

Feature Request / Improvement

We'd like to support writes to Bucket partitioned tables by leveraging pyiceberg_core package of iceberg-rust.

• [x] Expose Bucket Transform through PyO3 on pyiceberg_core (https://github.com/apache/iceberg-rust/pull/556)
• [ ] Release pyiceberg_core 0.1.0
• [ ] Add pyiceberg_core 0.1.0 optional dependency and Bucket Transform support in PyIceberg

I'm willing to help with the release about pyiceberg_core.
