使用 ISD2360 和 PIC18F4458 实现清晰的语音提示和高质量音频播放

 * @file main.c
 * @brief Speaker 2 Click example
 *
 * # Description
 * This example demonstrates the use of the Speaker 2 Click board. It initializes the board
 * and plays predefined voice messages or sound effects through the speaker module.
 * Supported voices include numbers (ONE to SIX) and sound effects like FAST BEEP.
 *
 * The demo application is composed of two sections:
 *
 * ## Application Init
 * Initializes the logger module, configures the Speaker 2 Click board, and applies the
 * default settings to reset the device, power it up, verify communication, and load an example
 * audio project into the device memory.
 *
 * ## Application Task
 * Sequentially plays predefined voice messages and sound effects from the Speaker 2 Click board
 * while logging the playback status (DONE or ERROR) for each sound.
