Thanks for the guidance! I have updated the PR to adhere to aeon's deprecation policy:

• Set znormalized="deprecated" default in SAX.__init__ with the # TODO remove 'znormalized' in v1.7.0 removal comment.
• Preserved backward compatibility by raising a FutureWarning (stacklevel=2) and mapping znormalized to znormalize.
• Updated docstrings and added unit tests for the deprecation warning, default sentinel, and value mapping.
• Updated the PR title prefix to [DEP].
