v2 uses KCL-2.5.8 which has known issues, please release a version that uses KCL-2.6.1

Could you please release a new 2.x version of amazon_kclpy that uses Java KCL-2.6.1?

The latest version of amazon_kclpy v2 is 2.1.5 and it uses Java KCL-2.5.8 which has some issues that under rare condition can block shard processing when stream capacity changes. There is KCL-2.6.1 which solves the problem, amazon recommend to update all apps that uses <=2.6.0 to use 2.6.1, see an important notice here: https://docs.aws.amazon.com/streams/latest/dev/kcl.html.

I guess the change is as simple as bumping version in pom.xml on 2.x branch and releasing.
