text: Title: cannot import aimstack without aimos package
  Body: ## ❓Question
  
  I'm trying to setup a Langchain debugger on Windows. Since `aimos` cannot be installed on Windows I installed `aimstack` and have the following code:
  
  ```
  
  def get_callbacks() -> list:
      callbacks = []
      aimos_url = os.environ["AIMOS_URL"]
      if aimos_url:
          try:
              from aimstack.langchain_debugger.callback_handlers import \
                  GenericCallbackHandler
              callbacks.append(GenericCallbackHandler(aimos_url))
          except ImportError:
              pass        
      return callbacks
  ```
  
  For some reason I'm getting ImportError. I've checked that correct venv is used and double checked I've installed `aimstack`. Please help
