Support for DynamoDB streams?

[mike-gore-cko]

It appears that the latest version of this library now only supports KCL v2.X. Are there plans to provide support for KCL v1.X? We need to be able to subscribe to a DynamoDB stream.

The only way I can get v1.X support working is to fork the repo & revert to the last commit before v2.X support was introduced, but that also means I would need to update that commit to support .NET 6. However, it's not clear what state the repo was in e.g. outstanding issues.

We could use Lambda instead, but the main issue there is we want to drive our idempotency checks on the stream checkpoint, which Lambda does not provide access to as we need to be able to obtain a shard id. There also appears to be an issue with Lambda where a successful invocation does not always progress the checkpoint which creates major issues for our use case.
