feat: Add new dependencies and SunoApi class for audio generation

functionality

Added new dependencies for axios, pino, and user-agents in the
package.json and pnpm-lock.yaml files to support audio generation
functionality. Additionally, implemented a new SunoApi class in the lib
directory to handle the audio generation process, including functions
for generating, customizing, and retrieving audio content from the
Suno.ai API. This addresses the need for enhanced audio processing
capabilities and lays the groundwork for efficient integration with the
Suno.ai API. No issues are associated with these additions.
