[bug] No way to use Manifest asynchronously

[irgolic]

Describe the bug As it stands, guardrails is invoked async if a coroutine/async callable is passed to the __call__ method of the guard. Manifest uses the same object for both sync and async. While there is plumbing for using manifest async (also tested and bugfixed in https://github.com/guardrails-ai/guardrails-internal/pull/12/commits/438d67e756f72df6b6568c55ee4830387500f3bb), there's currently no interface to access it.
