Feature Request: Add LaTeX to Markdown Conversion Support

I tried to use markitdown to convert latex to markdown, but unfortunately markitdown doesn't seem to support latex at the moment.

❯ markitdown new.tex -o new.md
Traceback (most recent call last):
  File "/usr/bin/markitdown", line 8, in <module>
    sys.exit(main())
             ~~~~^^
  File "/usr/lib/python3.13/site-packages/markitdown/__main__.py", line 186, in main
    result = markitdown.convert(args.filename, stream_info=stream_info)
  File "/usr/lib/python3.13/site-packages/markitdown/_markitdown.py", line 256, in convert
    return self.convert_local(source, stream_info=stream_info, **kwargs)
           ~~~~~~~~~~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

    guesses = self._get_stream_info_guesses(
        file_stream=fh, base_guess=base_guess
    )
  File "/usr/lib/python3.13/site-packages/markitdown/_markitdown.py", line 616, in _get_stream_info_guesses
    if result.status == "ok" and result.prediction.output.label != "unknown":
       ^^^^^^^^^^^^^
AttributeError: 'MagikaResult' object has no attribute 'status'

Reproduce the reported markitdown new.tex -o new.md command, then inspect markitdown/_markitdown.py, especially convert_local and _get_stream_info_guesses. Done means a LaTeX file can be converted to Markdown without the reported MagikaResult traceback; the issue does not define the expected Markdown output.
