Contributing changes back to Apache Arrow/Parquet

[nevi-me]

Hi, I'm one of the Arrow commiters on the Rust implementation.

I've just stumbled upon your repo.
The PR that you based your work on, was merged in the past few weeks, and we now have parquet_derive as a crate.
Is there any additional work that you continued on, which the community could benefit from?
If so, would you be able to submit a PR to upstream them?

Thanks ❤
