Describe the enhancement requested
Dictionary arrays are not supported currently in dotnet flight implementation
Initially implement dictionary support where dictionary messages are resent with every record batch. This is not as optimal as proper dictionary reuse and delta support but will unlock ability to leverage dictionary batches over flight. Related work in Rust Arrow implementation: apache/arrow-rs#4896
