separate DF SDK classes from DF worker classes

fix typo

DurableSDK now compiles by itself

Allow ExternalSDK to handle orchestration

document next steps

allow external SDK to set the user-code's input. Still need to refactor this logic for the worker to continue working with old SDK

add import module

supress traces

avoid nullptr

pass tests

fix E2E tests
