**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** In https://github.com/apache/arrow/pull/49296 @pitrou found a clever optimization for delta packed decoding. If the bitwidth for a miniblock is 0, meaning a constant delta throughout the miniblock, then some optimizations can be made. Some pretty dramatic speedups were presented for the arrow-cpp decoder. **Describe the solution you'd like** Explore implementing a similar optimization in the parquet crate. **Describe alternatives you've considered** Leave it as is **Additional context** -- This is an automated message from the Apache Git Service.
