feat ✨: Added new header files AudioLevelTracker.h, Config.h, I2SConfig.h, and updated Arduino code for improved I2S communication and dynamic range limiting.

- Added a new header file `AudioLevelTracker.h` to track audio levels with a history of up to 3 seconds and a maximum range limit.
- `Config.h` has been added with new serial and I2S configurations. The aim is to configure these peripherals for audio processing.
- Added new header file `I2SConfig.h` with setup functions for initializing and reading from I2S interface.
- The `AudioLevelTracker.cpp` file has been updated to include functionality for tracking the maximum audio level over a specified duration.
- Initial setup for I2S communication with a microphone.
- Updated `Arduino` code with improved I2S configuration and dynamic range limiting.
