Seek operation in async client

[The-Q]

Is there any reason why seek operation is not supported in async facade?

The async facade will be removed. It might be revived in a supporting library later on

Here's the separate project for the async facade: https://github.com/fmjrey/kinsky-async/
It does support a :seek op but it needs PR #57 in this project to be able to function properly.
