Client for the DataWrangler Environment.
Connects to the DataWrangler server over WebSocket for efficient
multi-step data cleaning interactions.
Example:
>>> with DataWranglerEnv(base_url="http://localhost:8000") as client:
... result = client.reset(task="task_1_easy")
... print(result.observation.response)

... result = client.step(DataWranglerAction(message="profile"))

Example with Docker:

>>> try:
... result = client.reset(task="task_1_easy")
... result = client.step(DataWranglerAction(message="find_missing"))
