Support more formats

Why it matters

This feature enables users to write data to Iceberg tables using additional data formats (ORC and Avro), expanding flexibility and compatibility with different big data processing frameworks and storage requirements.

How to use it

When creating or inserting data into Iceberg tables, specify the desired output format as ORC or Avro. For example, set the appropriate table format settings or use relevant table engines that support these formats in your INSERT statements.
