If "sentiment" is on, field access fails due to incorrect from_dict() call on StrEnum

What is the current behavior?

Location:
.venv/lib/python3.12/site-packages/deepgram/clients/listen/v1/rest/response.py
lines 169-173

Problematic code:

def __getitem__(self, key):
    _dict = self.to_dict()
    if "sentiment" in _dict:
        _dict["sentiment"] = Sentiment.from_dict(_dict["sentiment"])  # this line 
has no from_dict method
    return _dict[key]

The __getitem__ method in the Deepgram response class attempts to call
Sentiment.from_dict() on the sentiment field, but Sentiment is a StrEnum that
doesn't have a from_dict() method. This causes an AttributeError when accessing
any field from the response object when sentiment data is present.

Steps to reproduce

1. Make a transcription request that returns sentiment analysis data
2. Try to access any field from the response object using bracket notation (e.g.,
   response["results"])
3. The error occurs in the __getitem__ method when it tries to process the
   sentiment field

Expected behavior

The response object should allow normal field access without errors.

Suggested fix:
Since Sentiment is a StrEnum, the sentiment value is already in the correct format
and doesn't need conversion. The problematic lines should be removed or the
sentiment field should be handled differently.
