Adds a new CTest unit test that performs a full, end-to-end verification of the 'spectool analyze' command.
The test programmatically generates a sine wave, saves it as a .wav file, executes the spectool executable as a subprocess to analyze the wave, and then verifies the integrity of the resulting .spec file.
This ensures the analysis pipeline (WAV decoding, windowing, FDCT, and file I/O) works correctly.

Leverages the built-in MP3 decoder in miniaudio to allow spectool's 'analyze' command to process .mp3 files in addition to .wav files.
Updates the tool's command-line help text and the project's HOWTO.md to reflect the new capability.

Adds a multi-voice, real-time audio synthesis engine that generates sound from spectrogram data using an Inverse Discrete Cosine Transform (IDCT).
Key features:
- A thread-safe, double-buffered system for dynamically updating spectrograms in real-time without interrupting audio playback.
- Core DSP components: FDCT, IDCT, and Hamming window functions.
- A simple sequencer in the main loop to demonstrate scripted audio events and dynamic updates.
- Unit tests for the new synth engine and Hamming window, integrated with CTest.
- A file documenting the build process, features, and how to run tests.
