Add opus encoder and improve logging for audio streams

[chicco-carone]

This pull request includes several improvements and feature additions to the snapstream.ts file, focusing on replacing console statements with a custom Logger class for better logging and adding support for Opus decoding.

Logging Improvements:

• Replaced all console statements with the Logger class for improved logging consistency and control in AudioStream, TimeProvider, OpusDecoder, FlacDecoder, and SnapStream classes.

Opus Decoder Integration:

• Added opus-decoder dependency to package.json for Opus decoding support.
• Implemented OpusDecoder class with methods for initialization and decoding of Opus audio streams.

Code Cleanup:

• Removed duplicate @types/node dependency from package.json.
• Cleaned up commented-out console statements and replaced them with appropriate logger calls in FlacDecoder and TimeProvider classes.

Miscellaneous:

• Added Logger class import and initialized logger instances in various classes to facilitate the new logging mechanism.
• Replaced the majority of commented console.log statements with logger.debug statements so that if needed only the log level needs to be changed to show debug info.

Also I accidentally pressed the shortcut on vscode to format the code with prettier which made this pr completely unreadable so i reverted it but it could be useful to implement a linter process when pushing to git or at least running manually prettier on the whole codebase to make the code more cohesive and follow a standardized format.

Thanks! I think the pnpm-lock.yaml file is not needed, right? Can you please remove it from the PR?
The CI (npm ci) fails because the package-lock.json file is not updated, as also described on Stackoverflow.
Could you also please make the PR "opus only"? I like the idea of having some more sophisticated logging and there seem to be a lot of "ready to use" 3rd party loggers available, which I would like to have a look at, before using a hand-crafted logger.

Sorry for the pnpm thing. Since i use pnpm when I work on my project I forgot it. I'll also remove the logging thing.

Edit: btw you can take a look at pino to use as a logger since its pretty simple to implement and should handle well lots of logs when debugging audio streams

Moved to #129 to clean the pr
