[PR] [client] Add support of column value compression [fluss]

zuston opened a new pull request, #4183:
URL: https://github.com/apache/fluss/pull/4183

   ### Purpose
   
   Primary-key tables can contain large `BYTES` columns that are transferred and stored without compression, increasing network bandwidth, storage usage, and write costs, especially for the multi-model columns. 
   
   This change adds per-column `LZ4` or `ZSTD` compression on the client side. Each compressed value uses a self-contained envelope containing a magic number, version, codec, original length, and payload. Readers detect and decode it transparently by default, while legacy uncompressed values remain compatible. 
   
   ### Brief change log
   
   <!-- Please describe the changes made in this pull request and explain how they address the issue -->
   
   ### Tests
   
   <!-- List UT and IT cases to verify this change -->
   
   ### API and Format

   ### Documentation
   
   <!-- Does this change introduce a new feature -->
