  Fix import of ApiWorkflowClient
  # Fix import of ApiWorkflowClient
  
  Currently, the following import statement (from the docs) does not work:
  ```python
  from lightly.api import ApiWorkflowClient
  ```
  
  TODO:
  - [x] We need to fix this by exposing the client in the `__init__.py` file. 
  - [x]  Make sure the other imports in the docs work as well
  
  </issue>
