### Rationale for this change Enables the use of custom allocators when reading column data with both buffered and unbuffered readers. ### What changes are included in this PR? Custom Allocator Support: - Modified utils.NewBufferedReader to accept memory.Allocator parameter - Added BufferedReaderV2 interface which extends BufferedReader with Free() and Buffered() methods - Added NewBytesBufferReader for allocator-backed byte buffers - ReaderProperties.GetStreamV2() uses the configured allocator for all buffer allocations, ReaderProperties.GetStream uses the wrapper around the default Go allocator to maintain original behavior ### Are these changes tested? - All existing unit tests pass with refactored implementation - Memory leak tests in TestReaderPropsGetStreamWithAllocator and TestReaderPropsGetStreamBufferedWithAllocator verify proper cleanup ### Are there any user-facing changes? New Features: - Users can now provide custom allocators via ReaderProperties to control memory allocation during page reading Breaking Changes: - utils.NewBufferedReader now requires a memory.Allocator parameter (pass nil for default) - new BufferedReaderV2 interface Closes #540 -- This is an automated message from the Apache Git Service.
