Subject: [PATCH] feat(include/audio): Add sound configuration loading and
 extended sound pack structures
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Introduce API to load sound configurations and expand SoundPack with richer audio data for multi‑key mappings and generic press handling, enabling more flexible audio management.

New Features
- Added `load_sound_config` prototype in `include/audio/config.h`.

Enhancements
- Extended `SoundPack` with generic press arrays, release data fields, and multi‑key mapping structs.
- Added `AudioVoice` struct and `MAX_MIXER_VOICES` for voice management.
- Added `generic_press_data`, `generic_press_samples`, `release_data`, and `release_samples` fields.
