Pekko support for scala client

[utkuaydn]

Are there any plans to include support for Pekko Streams in the future?

Hi @utkuaydn,

thanks for your suggestion. Currently we don't plan any new feature for Scala client. Is this something you would be willing to help with? All PR is welcome and we will be happy to review your submission.
