Add new sound files and update dependencies

- Added various sound files to the soundboard, including insults, quotes, and sound effects.
- Introduced new dependencies: ffmpeg-python (version 0.2.0) and pydub (version 0.25.1) for audio processing.
- Updated the lock file to reflect the new packages and their respective versions.
- Added .gitignore files in the sounds/stream and sounds/temp directories to exclude unnecessary files.
