URL: https://github.com/apache/arrow-adbc/issues/2526

   ### What happened?
   
   Running SQL queries through the Snowflake ADBC driver, from Rust, can cause 
a crash due to buffer alignment issues.
   
   ```
   thread 'main' panicked at 
~/.cargo/registry/src/index.crates.io-6f17d22bba15001f/arrow-buffer-53.4.0/src/buffer/scalar.rs:143:17:
                                                                        
   Memory pointer from external source (e.g, FFI) is not aligned with the 
specified scalar type. Before importing buffer through FFI, please make sure 
the allocation is aligned.
   ```
   
   This is known problem for Rust [1] when it's consuming buffers from systems 
that don't care as much about alignment as `rustc` does. It's been fixed in the 
FFI integration with Python [2].
   
   The ADBC Rust driver wrapper should do the same. How can it trigger the 
`ArrayData::align_buffers()` call that makes the Python FFI integration work 
without alignment issues?
