add new codec: Zstandard

[sycured]

Companies like CloudFlare use Zstandard instead of Snappy with Kafka: https://blog.cloudflare.com/squeezing-the-firehose/

Hi @sycured I'd love to see this merged!

I guess the PR did not move forward because of the tests. Could you update your PR for clippy to be happy (and maybe a more recent zstd, I think there has been some updates).

Cheers

Hi!
This project has been donated to Apache Avro - https://github.com/apache/avro/tree/master/lang/rust.
Maybe the PRs should be re-targeted ?
I am not an Apache Avro committer but I'd like to help with the development of the Rust implementation!

Hello,
Thank you for this information and effectively, I'll propose my PR tonight to Apache Avro.
