Implement the position delete writer

After we finish #275, we can implement the position delete writer based on this framework.

There is a [rust implementation](https://github.com/icelake-io/icelake/blob/main/icelake/src/io_v2/base_writer/position_delete_writer.rs) that can be referred to in icelake. But better design is acceptable.

related spec:
https://iceberg.apache.org/spec/#position-delete-files

Start by reviewing the work in #275, then compare this repository's writer framework with icelake/src/io_v2/base_writer/position_delete_writer.rs. Read the Iceberg position-delete-files specification to define the expected behavior; done means a position delete writer is implemented against the framework and conforms to that specification.
