Zstd support

Hello,
Are there any plans to support zstd compression for kafka output?
zstd support was fixed in sarama 1.26.0

Thanks for posting here! I see we are aware of the problem with sarama here beats/config.go at 621c9e2cf614235a104a170229cb324ebfbea811 · elastic/beats · GitHub. @faec Do you know if we have any plan?
