[WIP] Add sound playback functionality with image display integration

[Copilot]

Thanks for asking me to work on this. I will get started on it and keep this PR's description up to date as I form a plan and make progress.

Original prompt

The task is to create a new source code file in the Freenove_ESP32_S3_Display GitHub repository that integrates and combines sound playback functionality with the ability to display pictures on the ESP32-S3 Display. This enhancement leverages the primary capability of the repository, which is compatible with FNK0104 hardware and is primarily written in C++.

The solution should include:

1. Sound Playback Functionality: Code to enable audio playback on supported hardware components. The solution should consider both predefined sound files and tones generated during runtime by the ESP32.

2. Picture Displaying: Integrate or reuse existing functionality to show images on the screen.

3. Combined Demonstration: A feature or routine that shows relevant images on the display while playing corresponding audio. For instance, an image of a guitar could be displayed alongside the sound of strumming.

4. Documentation: In-code comments and one README.md section detailing how to test, execute, and expand this new feature.

5. Dependencies: Explicit instructions for any additional libraries (e.g., for playing sound or decoding image files).

This will extend the repository's capabilities demonstratively, making it easier to work on multimedia projects for ESP32.
