Hello,

I am pretty stoked to report  progress on a Rust Variant implementation
(see epic here[0]).

1. We have added example binary data in parquet-testing[1] (Thanks Micah
for the review and merge)
2. Jiaying's prototype [2] is looking good and we are preparing to start
merging it in pieces
3. I have created a PR to add a parquet-variant crate to arrow-rs[3]
(looking for a review 🎣)

Once we have the parquet-variant crate merged, I expect a series of PRs
that incrementally adds support for different parts of the Variant
specification. Once this is done, we will move on to integrating it into
the parquet decoder.

Exciting times,
Andrew
