[cookie0o]

added a auto Streamer mode detection and made some small improvements to the readme.md

Thank you for contributing, but this commit has some major flaws:

1. Naming conventions: https://peps.python.org/pep-0008/#function-and-variable-names
   Functions are lower case letters with underscores between the words. Like def is_streamer_mode(). Also, the is_streamer_mode function supposed to be inside the Sonar class, not next to it.

2. Why did you copy the whole sonar.py in a new file before adding new features to it? You could just edit the one in src/steelseries_sonar_py/sonar.py

3. What does _ = None does in the 7th row? Why is it neccessary there?

Thank you for contributing, but this commit has some major flaws:

1. Naming conventions: https://peps.python.org/pep-0008/#function-and-variable-names
   Functions are lower case letters with underscores between the words. Like `def is_streamer_mode()`. Also, the `is_streamer_mode` function supposed to be inside the `Sonar` class, not next to it.

2. Why did you copy the whole `sonar.py` in a new file before adding new features to it? You could just edit the one in `src/steelseries_sonar_py/sonar.py`

3. What does `_ = None` does in the 7th row? Why is it neccessary there?

1. Didn't know it will change the Name

2. My Stupidity

3. Leftover from testing

Will change all the things and make a new commit, but thanks for the comment!
