Refactor: Use a single definition of MAX_SEGMENT_SIZE in Segment

- Changed MAX_SEGMENT_SIZE in Segment.java to be public.
- Updated SegmentDataUtils.java to use the MAX_SEGMENT_SIZE from Segment by importing it statically.
- Removed the redundant definition of MAX_SEGMENT_SIZE in SegmentDataUtils to avoid duplication.
